The NRP-Z91 is a USB Power meter with a diode head.
notes[edit]
- 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-FU : 0x0004
FSH-Z1 : 0x000b
NRP-Z11 : 0x000c
NRP-Z22 : 0x0013
NRP-Z23 : 0x0014
NRP-Z24 : 0x0015
NRP-Z51 : 0x0016
NRP-Z52 : 0x0017
NRP-Z55 : 0x0018
FSH-Z18 : 0x001a
NRP-Z91 : 0x0021
NRP-Z81 : 0x0023
NRP-Z37 : 0x002d
NRP-Z27 : 0x002f
<serial number> you can find on your sensor. Serial number is number
with 6 digits. For exampel 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 sensor. You can use star, 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.
