9. Calculate the Absolute Amplitude Accuracy:
Delta = RSA5100B reading - Power Meter reading
Readings are in dBm, error is in dB.
10. Record the Absolute Amplitude Error in the test record. (Limits are shown in
the test record.)
11. Repeat steps 6 through 10 for frequency spans of 1 MHz and 41 MHz (Option
B40, B85, and B16x).
1. Connect the RF generator, power splitter, power meter, and RSA5100B.
(See Figure 10.)
2. Reset the RSA5100B to factory defaults: select Setup > Preset (Main).
3. Select Tools > Alignments and select Align Now.
4. Set the RSA5100B:
Reference Level
Setup > Amplitude > Internal Settings > Ref Level
Center Frequency
Setup > Settings > Center
Span
Setup > Settings > Freq & Span > Span
LF Path
Setup > Acquire > Input Params
5. Set the RF Generator:

6. Select the Peak key on the Markers control bar to set the Reference Marker
(MR) to the carrier peak.
7. Record the reading on the Power Meter and on the RSA5100B marker
amplitude.
8. Calculate the Absolute Amplitude Accuracy:
Delta = RSA5100B reading - Power Meter reading
Readings are in dBm, error is in dB.
9. Record the Absolute Amplitude Error in the test record. (Limits are shown in
the test record.)
