49. Absolute Amplitude , V ernier , and P ower Sweep A ccuracy , HP 8591EM Option 010
7. Subtract 020 dBm (87 dBV) from the power level displayed on the
measuring receiver and record the result as TR Entry 1 of the performance
verication test record as the Absolute Amplitude A ccuracy .

9. Press RA TIO on the measuring receiver . P ower levels now readout in dB
relative to the power level just measured at the 010 dBm (97 dBV) output
power level setting.
10. Set the SRC POWER to the settings indicated in T able 2-63. At each setting,
record the power level displayed on the measuring receiver in T able 2-63 .
11. Calculate the absolute vernier accuracy by subtracting the SRC POWER
setting and 10 dB from the Measured P ower Level for each SRC POWER
setting in T able 2-63.
V ernier A ccuracy = Measured P ower Level 0 SRC PO WER 0 10 dB
V ernier A ccuracy = Measured P ower Level 0 SRC PO WER + 38.76 dB
12. Locate the most positive and most negative absolute vernier accuracy
values for SRC POWER levels greater than 010 dBm (97 dBV) recorded
in T able 2-63 and record in the performance verication test record the
P ositive V ernier A ccuracy as TR Entry 2 and the Negative V ernier A ccuracy
as TR Entry 3.
P ositive V ernier A ccuracy dB
Negative V ernier A ccuracy dB
13. Locate the most positive and most negative Absolute V ernier A ccuracy
values for all SRC POWER levels in T able 2-63 and record below .
P ositive P ower Sweep A ccuracy dB
Negative P ower Sweep A ccuracy dB
14. Calculate the power sweep accuracy by subtracting the Negative P ower
Sweep A ccuracy recorded in the previous step from the P ositive P ower
Sweep A ccuracy recorded in the previous step . Record this value as
