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: f0.5 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.
