R&S®FSMR Measuring Receiver
One-box-solution for calibrating signal generators and attenuators
Level Measurement
The operating functions of the R&S® FSMR are tailored to the needs of level calibration over a wide level range. Any range switching is compensated for by an easy-to-use range-change calibration method.
Only a few operating steps are required:
Step 1: Set the measurement frequency. The FSMR measurement range is then automatically set to the level of the incoming signal (AUTORANGE function).
Step 2: Perform a reference measurement with the power meter by means of CAL ABS POWER. The FSMR is now ready for level calibration, which is indicated by the CORR field turning green
Step 3: Reduce the level of the device to be calibrated in the required steps and verify the level. If the test signal is outside the usable measurement range of the FSMR, the user is prompted to calibrate the adjacent range
Step 4: Calibrate the adjacent range with the RECAL key. The FSMR automatically switches the measurement range
