Rohde & Schwarz FSP7 - Checking if Filters; Checking Bandwidth Switching Level Accuracy

Performance Test R&S FSP
1164.4556.82 1.8 E-1
Checking IF Filters
Test equipment:
Signal generator (refer to "Measurement Equipment", item 3):
Frequency 128 MHz
Level  0 dBm
Test setup:  Connect RF output of the signal generator to RF input of the
R&S FSP.
Checking Bandwidth Switching Level Accuracy
Reference measurement (RBW 10 kHz)
Signal generator settings:
- Frequency:
128 MHz
- Level: -30 dBm
R&S FSP settings:
- [ PRESET ]
- [ AMPT : -20 dBm ]
- [ AMPT : RF ATTEN MANUAL : 10 dB ]
- [ FREQ : CENTER : 128 MHz ]
- [ SPAN : 5 kHz ]
- [ TRACE : DETECTOR : RMS ]
- [ BW : RBW MANUAL : 10 : kHz ]
Reference measurement:
 Set marker to peak of signal:
- [ MKR  : PEAK ]
 Set reference to peak of signal:
- [ MKR : REFERENCE FIXED ]
Checking level accuracy
R&S FSP settings:
- [ SPAN : {0.5 x RBW} ]
- [ BW : RBW MANUAL : {RBW} : ENTER]
Note:
To check the FFT filter, the resolution bandwidth has to be set manually
to FFT mode.
-[ BW : BW MODE : FFT ]
Measurement:
 Set marker to peak of signal:
- [ MKR  : PEAK ]
Evaluation:
The level difference is displayed in the marker field by the reading
´Delta [T1 FXD] {xxx} dB´.
