SUPPLEMENTAL CHARACTERISTICS

NOTE: Values in this table are not specifications. They are typical characteristics included for user information.

FREQUENCY CHARACTERISTICS	AMPLITUDE CHARACTERISTICS
FREQUENCY ACCURACY	AMPLITUDE RANGE AND ACCURACY
Frequency Cal	Dynamic Range

Adjusts digital FREQUENCY GHz readout. FREQUENCY CAL control may be used to calibrate 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. Alternate IF available at approximately 2.9925 GHz for all frequency bands (minimum frequency 25 MHz).

SPECTRAL RESOLUTION AND STABILITY Frequency Drift(Fundamentalmixing- n = 1 - or 1+)

At fixed center frequency after Zhour warmup:

< 25 kHz/lO minutes With temperature changes:

<200 kHz/"C

ResolutionBandwidth Shape

Approximately gaussian (synchronously-tuned, 4-pole filter).

Spectral Resolution

The following graph shows typical spectrum analyzer resolution for different resolution bandwidths.

Frequency

SIGNAL RESOLUTION VS. FREQUENCYSEPARATION

Maximum power ratio of two signals simultaneously 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.
