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.
