ENSOR

The Model 3200 smart sensor power meter is specifically designed to be integrated into test systems.It features highly accurate complex signal measurement and is controlled with an RS/232 serial interface. You get the flexibility of a power meter that can accuartely measure all digital modulations schemes, such as QPSK 3/4 Coding, QPSK 7/8 Coding, Turbo-coding, 256 QAM, CDMA, and more..., without the fancy packaging or price.

1

Incrorrect syntax or out of range parameters will result in an error.

2

Linear power is reported as an integer number of picoWatts. Log power isreported in negative dBm with resolution to the 0.1 dBm. The decimal point and the tenths digit are required.

3

0=current measurement, 1=begin new reading using set averaging, 2=continu-ouse output Notes:

4

The =x is optional. If not sent, power is assumed as -20. Else, command isCA=-42.1 Parameters to be in format identical to measurement output andconsistent with the units selected

1

Spectral energy above 10 MHz.Relative to reference reading taken within past 15 minutes or 3°C tempera-ture change. Sensor zeroing perfomed every 1 minute or following 1°C tem-perature change for input measurements below -40 dBm.

5

See attached error code list. Read, {Exx} where xx is error number

2

Power and grounding arrangement must not induce common mode offsetvoltage at RF connector of greater than 5mv dc or an ac signal greater than20 dB below the minimum signal to be measured.
