FORMAT MAGNITUDE, PHASE
MARKER MARKER CONT
MARKER1 = -20 dBm
Measurement:
Set test frequencies according to test report.
Perform reference measurement at a level of –20 dBm at the test frequency.
SOURCE POWER max. value to min. value
(0 dBm to –25 dBm at f = 20 kHz to 6 GHz,
– 3 dBm to –25 dBm at f = 6 GHz to 8 GHz)
Read the marker values (magnitude and phase) on the network analyzer, take
into account the reference value.
Values < source power min.:
RSM 10 dB
SOURCE POWER –15 dBm
New reference value Marker value +
deviation of the previous measurement
New measurement:
SOURCE POWER –25 dBm
New measured value Marker value – new reference value
RSM Increase attenuation by 10 dB,etc.
Model 50 and 60: Deviation from
reference value (–20 dBm): Permissible deviation:
20 kHz to 10 MHz +10 dB to +3 dB <1 dB <6°
+ 3 dB to –20 dB <0.2 dB <2°
-20 dB to –30 dB <0.5 dB <4°
-30 dB to –45 dB <1 dB <6°
10 MHz to 4 GHz +10 dB to +3 dB <1 dB <6°
+ 3 dB to 50 dB <0.2 dB <1°
50 dB to 60 dB <0.5 dB <4°
