FREQUENCY CHARACTERISTICS
FREQUENCY ACCURACY
Frequency Cal
Adjusts digital FREQUENCY GHz readout.
FREQUENCY CAL control may be used to cali-
brate the frequency readout on a known signal
or on the 35 MHz CAL OUTPUT signal.
FREQUENCY RANGE
Alternate IF
Regular IF approximately 3.0075 GHz. Alter-
nate IF available at approximately 2.9925 GHz
for all frequency bands (minimum frequency 25
MHz).
SPECTRAL RESOLUTION AND STABILITY
Frequency Drift
(Fundamental mixing
At fixed center frequency after Zhour warmup:
<
25 kHz/lO minutes
With temperature changes:
Resolution Bandwidth Shape
Approximately gaussian (synchronously-tuned,
4-pole filter).
Spectral Resolution

AMPLITUDE CHARACTERISTICS
AMPLITUDE RANGE AND ACCURACY
Dynamic Range
Maximum power ratio of two signals simultane-
ously present at the input that may be measured
within the limits of specified accuracy, sensitiv-
ity, and distortion (i.e., spurious responses):
>70 dB.
Frequency Response and Average Noise Level
The following graph shows typical frequency
response and average noise level versus fre-
quency.
