HP 8559A - 4-23. Reference Level Accuracy

MODEL 8559A PERFORMANCE TESTS
PERFORMANCE TESTS
4 - 23. REFERENCE LEVEL ACCURACY
SPECIFICATION:
Step Accuracy (steps referenced with
0 dB input attenuation):
- 10 dBm to - 80 dBm:
+ 0.5 dB
-10dBmto-100dBm: +1.0dB
Vernier Accuracy: f 0.5 dB
DESCRIPTION:
The reference level accuracy is tested over the range of
- 10 dBm to - 100 dBm by checking the IF gain steps in
1
dB/DIV (Log) and in LIN. The resulting maximum deviation in each case must be less than k0.5 dB from
- 10 dBm to - 80 dBm and less than k 1.0 dB from - 10 dBm to - 100 dBm.
