The DARE!! Instruments RPR1006A device driver is a Power Meter which is supported by RadiMation®.


Configuration

The following tabs are available in the advanced configuration of the DARE!! Instruments RPR1006A:

PowerMeterPanel.png


ScreenElementDescription.png Pre Wait Time Wait time before starting the measurement-loop. Can be used to wait for a signal generator, and or amplifier to stabilize.
ScreenElementDescription.png Measure The minimum amount of measurements in the measure loop. Continues to loop even if power level is stable.
ScreenElementDescription.png Wait Time The wait time between each measurement is taken, during the measurement-loop.
ScreenElementDescription.png Max. Difference If the measured power between each measurement in the measurement-loop, is less than this value. The measured power is stable. The measurement-loop will then stop.
ScreenElementDescription.png Max. Measure The maximum amount of measure times, for the measurement-loop


According to these settings, RadiMation® will perform a minimum of 3 power measurements with a wait time between the measurements of 75ms. If all those 3 measurements are within 0.1 dB, the power measurement is assumed to be stable, and RadiMation® will continue to average of the last 3 measurements. If the difference between the measurements is larger than the specified 0.1 dB, an additional power measurement will be performed, and the last 3 samples will be compared to the 0.1 dB difference again. At most 10 measurements will be performed if the difference between the 3 samples will not be within the specified 0.1 dB.

Both for the leveling, and the monitoring these settings can be set individually. The leveling is used, whenever RadiMation® is measuring the power, to regulate the signal generator. If the powermeter is only used as input, without regulating on it, then the monitoring settings are used.

More detailed information on how to achieve a fast and stable power measurement is available in Application Note 106: Powermeter parameter configuration.

ConfigurableFrequencyRangeTab.png

The frequency range of the DARE!! Instruments RPR1006A as provided by the manufacturer is shown and selected as default. It is possible to overrule these frequencies and to manual adjust the allowed frequency range of the DARE!! Instruments RPR1006A.

ScreenElementDescription.png Use default start frequency If the checkbox is checked, the default start frequency will be used as the lowest usable frequency in a test for this device.
ScreenElementDescription.png Custom start frequency If the Use default start frequency checkbox is unchecked, another start frequency (expressed in MHz) can be specified. The customized start frequency will then be used as the lowest usable frequency in a test for this device. The customized frequency can be a limitation or an extension of the default start frequency.
ScreenElementDescription.png Use default stop frequency If the checkbox is checked, the default stop frequency will be used as the highest usable frequency in a test for this device.
ScreenElementDescription.png Custom stop frequency If the Use default stop frequency checkbox is unchecked, another stop frequency (expressed in MHz) can be specified. The customized stop frequency will then be used as the highest usable frequency in a test for this device. The customized frequency can be a limitation or an extension of the default stop frequency.


Specifying a different frequency range can be useful if for example:

  • A device (like a coupler, antenna, injection device, cable, etc...) is still useable (but out of specification) outside the standard suggested frequency range.
  • An external mixer is used to measure an extended frequency range.
  • An up- or down-convertor is used to shift the frequency range.
  • A newer model of a device is present that has an extended frequency range, and still uses the same remote control commands.

Be careful changing these setting as RadiMation® is no longer able to verify if the DARE!! Instruments RPR1006A is used outside frequency range that is specified by the manufacturer. This may result to serious damage of your measurement device.

DeviceDriverReferenceTab.png

The settings on the Reference tab influence the measurement frequency that is communicated to the measurement device. The frequency that is forwarded to the measurement device can for example be used by the device to perform the measurement on the correct frequency, or use the correct internal frequency dependant correction or calibration factor on the measurement result. Normally it is desired that the measurement frequency is the same as the carrier frequency of the signal generator. In some situations it can however be required to communicate a different frequency to the measurement device. In such a situation the settings on the Reference tab can be modified.


ScreenElementDescription.png Signal generator frequency Selects that the actual carrier frequency of the signal generator is communicated to the measurement device. This is the default behaviour.
ScreenElementDescription.png Fixed reference frequency Selects that a fixed frequency (independent of the signal generator carrier frequency) is communicated to the measurement device.
ScreenElementDescription.png Signal generator frequency offset An additional offset frequency specified in MHz, that is added to frequency that is communicated to the measurement device. This value can be positive or negative, and defaults to 0.0 MHz.
ScreenElementDescription.png Specific reference frequency The fixed reference frequency specified in MHz that is communicated to the measurement device, when the Fixed reference frequency option is selected.


Warning-48px.png
Warning: When a different reference frequency is specified and communicated to the measurement device, it is only relevant for the measurement device. A correction file that is attached to the device driver in RadiMation® will still use the correction value that is specified for the actual signal generator carrier frequency.

DeviceDriverOptionTab.png


ScreenElementDescription.png Value Allows to select the filter that should be used in the measurement device. The possible filters are described in the manual of the DARE!! Instruments RPR1006A.


GPIB DeviceStream Configuration.png

On the Communication tab, the desired communication method can be selected and configured. Depending on the selected method, additional relevant settings are shown and can be configured.


ScreenElementDescription.png Communication Streams Selects the medium or method that should be used to communicate with the device. Depending on the capabilities of the device this can be one or more of:

See the Communication Settings in Chapter 15, on how to configure each of these methods.


DeviceDriverIdentification.png

On the Identification tab, the expected *IDN? response of the test and measurement device can be configured. It is used to determine if the correct test and measurement device is connected.


ScreenElementDescription.png Expected response The expected *IDN? response of a device. It can be changed in the case the commands are the same for another device for which no RadiMation® driver is available yet.
ScreenElementDescription.png Restore default Restores the original Exepected response.


DeviceDriverRadiCentreTab.png

There are several methods in which the DARE!! Instruments RPR1006A can be connected to the PC. The DARE!! Instruments RPR1006A can for example be connected directly to the PC, or through a plugincard in a RadiCentre 1 or a multi-slot RadiCentre. More information on how to use the RadiCentre is present in the product manual of the RadiCentre. The settings on the RadiCentre tab can be used to specify how the DARE!! Instruments RPR1006A is connected.

When the DARE!! Instruments RPR1006A is connected to a multi-slot RadiCentre, also the slot number in which the plugincard is fitted, should be specified.


ScreenElementDescription.png Directly to PC Specifies that the DARE!! Instruments RPR1006A is connected directly to the PC, without the use of a RadiCentre.
ScreenElementDescription.png RadiCentre 1 Specifies that the DARE!! Instruments RPR1006A is connected to a plugincard that is fitted in a RadiCentre 1.
ScreenElementDescription.png RadiCentre Multi-slot Specifies that the DARE!! Instruments RPR1006A is connected to a plugincard that is fitted in a multi-slot RadiCentre.
ScreenElementDescription.png Device ID Specifies the slot in the multi-slot RadiCentre in which the plugincard of the DARE!! Instruments RPR1006A is fitted.


The settings on this RadiCentre tab, only specifies if and which RadiCentre is used. The communication settings on the Communication tab specify the connection settings to communication with the measurement device.

The configuration on the Communication tab should be configured depending on the outgoing connection from the PC. Thus if Directly to PC is selected, the communication settings should be configured as what is actually used between the PC and the DARE!! Instruments RPR1006A itself. If RadiCentre 1 or RadiCentre Multi-slot is selected, the communication settings should be configured as what is actually used between the PC and the RadiCentre. In the configuration where a RadiPower is connected with USB to a Multi-slot RadiCentre, which is connected by GPIB to the PC, the communication settings of the RadiPower device driver should thus be GPIB.

If the DARE!! Instruments RPR1006A is for example connected to slot 3 of a multi-slot RadiCentre which has IP address 192.168.178.95 and is connected by LAN to the PC, the following settings should be configured in the device driver of the DARE!! Instruments RPR1006A:

  • RadiCentre tab
    • Connection type: RadiCentre Multi-slot
    • Device ID: 3
  • Communication tab
    • Communication Stream: VISA
    • LAN: 192.168.178.95


DeviceDriverSoftwareUpdateTab.png

The Software update tab can be used to update the firmware of the DARE!! Instruments RPR1006A.

ScreenElementDescription.png Firmware Specifies the filename of the firmware update file that should be used to update the firmware of the measurement device.
ScreenElementDescription.png Browse Allows to select the firmware update file.
ScreenElementDescription.png Update Firmware Starts the actual firmware update. First some checks are performed, and if those checks are successful, the actual firmware update is performed.
ScreenElementDescription.png Status Shows a message during the firmware update, indicating the performed action and the actual status.


Warning-48px.png
Warning: The firmware update can take a few minutes. During the actual firmware update the window can be non responsive, and Windows messages can be shown that the RadiMation® software is not responding. Ignore those messages and do not kill, abort or end the software. Also do not disconnect the connection between the DARE!! Instruments RPR1006A and the PC, while the firmware update is being performed.
