The 87230 series USB CW power sensor can realize continuous wave power measurement. As the
performance specifications are different by model, the user can select the suitable sensor according to
the characteristics and measurement requirements of signals to be tested as well as the specifications of
each sensor. The basic functions of the sensor are shown in Table 3.1. Please refer to
“7.3 Technical
Specifications”
of the User Manual for detailed description of specifications of each sensor.
3.2 Virtual Power Measurement Panel
The USB interface of the 87230 series USB CW power sensor conforms to the USBTMC (USB Test and
Measurement) protocol, which is a kind of enumerated equipment (namely, it can be found through the
viFindRsrc function of the VISA library). The vendor ID and equipment ID (decimal) are 1204 and 4100
respectively, and the serial number are as shown in each sensor.
The user can realize the remote control of the USB sensor through the VISA library; for the specific
configuration, please refer to the
Programming Manual of the 87230 Series USB CW Power Sensor , and
the virtual power test panel can also be used for the power test. The user shall install the version above
