Rohde & Schwarz FSP7 - Checking Frequency Response

R&S FSP Performance Test
1164.4556.82 1.23 E-1
Checking Frequency Response
Test equipment:
- N cable (refer to "Measurement Equipment", item 14)
- 10 dB attenuator (refer to "Measurement Equipment", item 20)
Frequency up to 3 GHz
Maximum attenuation < 0.2 dB
Test setup: Connect 10 dB attenuator to tracking generator output port. Connect
10 dB attenuator to RF input of the R&S FSP.
R&S FSP settings:
- [ PRESET ]
- [ NETWORK ]
- [ NETWORK : SOURCE POWER 0 dBm ]
- [ AMPT : RF ATTEN MANUAL : 20 dB ]
- [ AMPT : 0 dBm ]
- [ NETWORK : SOURCE POWER {level}]
{level} : 0 dBm; -10 dBm; -25 dBm
- [ BW : RES BW MANUAL : 1 kHz ]
- [ SWT : MANUAL : 2 s ]
Reference:
- [ FREQ : CENTER : 128 MHz ]
- [ SPAN : 0 Hz ]
Range 1:
- [ FREQ : START : 9 kHz ]
- [ FREQ : STOP : 100 kHz ]
Range 2:
- [ FREQ : START : 100 kHz ]
- [ FREQ : STOP : 1 MHz ]
- [ BW : RES BW MANUAL : 10 kHz ]
- [ SWT : AUTO ]
Range 3:
- [ FREQ : START : 1 MHz ]
- [ FREQ : STOP : 2 GHz ]
Range 4:
- [ FREQ : START : 2 GHz ]
- [ FREQ : STOP : 3 GHz ]
Measurement:
Reference:
Set Marker to 128 MHz (=Ref
128 MHz
).
All other ranges:
Set marker to peak:
- [ MKR  : PEAK ] (=L
max
)
Set marker to minimum value:
[ MKR  : MIN PEAK ] (=L
min
)
Evaluation:
Calculate frequency response:
Maximum = L
max
- Ref
