CAL Key (Calibration)
This section describes the menu displayed when the SHIFT and 7 (CAL) keys are pressed.
Cal All
Performs calibrations for all items to see if they meet the specifi-
cations.
Perform them before taking measurements.
Total Gain
Performs calibrations with more accuracy than Cal All, because
user-defined measurement conditions are used. Set the conditions
first before the calibrations.
Cal Each Item
Displays the Cal Item menu used for each calibration.
Input ATT
Measures the Input Attenuator switching error and calibrates it.
IF Step AMP
Measures the IF Step AMP switching error and calibrates it
RBW Switching
Measures the switching error for the IF Filter resolution band-
width and calibrates it.
Log Linearity
Measures the linearity of the ordinate axis at a range of 10 dB/ div
to 0.5 dB/div on the LOG scale and calibrates it.
Amplitude MAG
Measures the switching error at a range of 10 dB/div to 0.5 dB/
div on the LOG scale and calibrates it.
PBW
Measures PBW (noise power bandwidth) at a resolution band-
width range of 10 Hz to 10 MHz and calibrates it.
Cal Corr ON/OFF
Toggles the calibration factor function on or off.
ON:
Calibration is performed using the calibration factor ob-
tained by Cal All or Cal Each Item.
OFF:
Turns off the calibration factor function.
Cal Sig Level
Sets the calibration signal’s output level.
more 1/2
Displays the CAL(2) menu.
Cal 10 MHz Ref
Allows you to enter a correction value in relation to the 10 MHz
reference frequency and displays the Cal Ref menu.
NOTE
The above statement does not apply to spectrum analyzers
with OPT 23 installed.
Coarse
Allows you to enter a coarse correction data to the 10 MHz refer-
ence frequency.
