normalization procedure
Drift
Long Term(One Year) ±2 PPM/year
Short Term(SPAN/DIV ≤20 kHz) All except Option 50 and Option 75:
≤400 Hz up to 1.8 GHz
Option 50 and Option 75: 500 Hz above
1.8 GHz
With frequency corrections enabled
Readout Resolution 1kHz or 1 Hz (counter readout), menu

Frequency Span/Div
Range Using
[SPAN/DIV][ y]and [SPAN/DIV] [ b]
buttons, selections in a 1--2--5sequence
Using the keypad or UTIL menu,
select any value from
100 MHz/div to 1 kHz/div.
In MAXSPAN,
180 MHz/div (All except Option 50 and
Option 75) or
215 MHz/div (Option 50 and Option 75)
In ZERO SPAN,0 Hz/ div
Accuracy/Linearity Within 3% Measured over the center 8 divisions
Flatness
(Relative to the Reference Level at 100 MHz)
All instruments:
±2dB9KHzto1.8GHz
Option 50 and Option 75: ±3 dB above
1.8 GHz
Measured with 10 dB of RF Attenuation
and PREAMP off
Flatness is affected by:
HInput voltage standing-wave ratio
(VSWR)
HGain variation
HMixer conversion
