The NRP-Z91 is a USB Power meter with a diode head.

Notes

• The driver can only be used if the program NRPView, 1.0.27 and above, from R & S is installed. When installing the program make sure that you install all the items. if you do not do this, some dll's will not be copied.
• Setting the resolution higher will make the measurement slower because the power meter is taking more samples and perform an average over the samples. this is done dynamically depending on the power measured.
• The syntax for the Instrument Descriptor is following:

USB::<vendor Id>::<product Id>::<serial number>

where <vendor Id> is 0aad for Rohde&Schwarz

     <product Id> depends on the sensor
                      NRP-Z21 : 0x0003

                      NRP-Z27 : 0x002f
     <serial number>  you can find on your sensor. Serial number is number
                      with 6 digits. For example 9000003

Examples: "USB::0x0aad::0x000b::100000"

You can use '*' for product id or serial number. We suggest full resource descriptor, when you have connected more sensors. You can use asterix, when one sensor is connected.

• RadiMation Error: -1074001424("Instrument status error"), when doing a zero of the power meter. the power on the head is too much, decrease the power and try again.

dll(s) needed

The dll needed to use this device is changed by Rohde & Schwarz. so now you can use:

• NrpControl2.dll
• rsnrpz_32.dll

To get these dll's install the vxipnp driver from the CD supplied with the device.

Example of installation

Please go the official website of the manufacturer Rohde & Schwarz and go to the page of your R&S®NRP Average Power Sensor model. For example: [1]

Apparently the required component for this driver is the R&S®NRP-Toolkit. Install this toolkit first: [2]

Select Drivers from the menu on the right side of the web page. Now scroll down to the table of Instrument Driver and download the VXIplug&play x86 Driver rsnrpz driver. Install these Rohde & Schwarz drivers: http://cdn.rohde-schwarz.com/pws/dl_downloads/dl_driver/rsnrpz/rsnrpz_vxipnp_2_37_0_32bit.exe

Afterwards the dll’s should be installed at C:\Program Files (x86)\IVI Foundation\VISA\WinNT\Bin\ and C:\Windows\SysWOW64\.
