ZVx Test Procedure (ZVM & ZVK)
1127.8500.60 5.9 E-2
5.2.2 Checking the Receiver Specifications
5.2.2.1 Absolute Accuracy
Test equipment: Signal Generator SMR40 with option SMR-B11
Power Splitter PC 3.5 (ZVM) or Power Splitter PC 2.92 (ZVK)
NRVD with sensor NRV-Z52 (ZVM), NRV-Z55 (ZVK)
Connecting cable SMR40 => power splitter
BNC cable to frequency synchronization.
Test setup: ½ Synchronize SMR40 with network analyzer.
½ SMR40 frequency = measurement frequency.
½ Connect SMR40 to power-splitter input.
½ Connect an output branch of the power splitter to PORT1 or PORT2 (INPUT B1,
INPUT B2 if a suitable receiver step attenuator is installed).
½ Connect sensor to second output branch of power splitter.
Settings on network analyzer:
PRESET
SWEEP SINGLE POINT
CENTER Measurement frequency
AVG IF BW 100 Hz
MEAS INPUT b1, DRIVE PORT2
INPUT b2, DRIVE PORT1
MODE EXTERNAL INPUT b1
INPUT b2
MARKER Marker
Measurement:
½ Set measurement frequencies (SMR, ZVM/K) according to test record.
½ Set level to -2 dBm on SMR.
½ Read marker value on ZVM/K.
½ Read measured value on NRVD.
Permissible deviation from nominal level (approx. -10 dBm, "exact" value = measured
value on NRVD) applied to PORT1 or PORT2 (INPUT B1, INPUT B2 if a suitable
receiver step attenuator is installed).
Deviation = marker value ZVM/K - measured value NRVD
