Hameg HM8135

The Hameg HM8135 device driver is a Signal Generator which is supported by RadiMation^®.

Configuration

The following tabs are available in the advanced configuration of the Hameg HM8135:

The frequency range of the Hameg HM8135 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 Hameg HM8135.

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.

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.

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.

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 Hameg HM8135 is used outside frequency range that is specified by the manufacturer. This may result to serious damage of your measurement device.

Connection methods

USB

The Hameg signal generator can be controlled by RadiMation^® by USB connection. This does require the installation of a specific windows driver provided by Rohde & Schwarz.

Note the following when setting up to control the Hameg HM8135 by USB:

The device comes available as a separate 'HAMEG Measurement Devices' category in the Windows Device manager. It is necessary to enable the 'Load VCP' option of the driver in the Windows Device manager. Then reconnect the USB again, and load the additional USB drivers.

Windows 11 support

The Windows USB driver provided by Rohde & Schwarz are not supported on Microsoft Windows 11 and newer. As an alternative the driver can be controlled using the hardware RS232 communication port of the Hameg HM8135.

RS-232

The following communication settings can be used:

Baudrate: 4800

Data bits: 8

Parity: None

Stop bits: 1
