CAL Key (Calibration)
This section describes the menu displayed when the SHIFT key and the 7 (CAL) key are pressed.
Cal All
Executes all calibration routines.
CAUTION: Do not perform a PRESET operation (SHIFT, PRESET)
while calibrating the spectrum analyzer because this will
erase all calibration data.
Total Gain
Measures the absolute error using a resolution bandwidth of 300
kHz, and the calibration signal output of both -15dBm and 1dB/
DIV.
Each Item
Changes the display to the Each Item menu.
IF Step Amp
Measures the IF Step AMP switching error and calibrates it.
RBW Switch
Measures the switching error for the IF Filter resolution band-
width and calibrates it.
Log Linear
Measures the linearity of the ordinate axis at a range of 10 dB/
DIV to 1 dB/DIV on the LOG scale and calibrates it.
AMPTD OFS
Calibrates the level offset in the LOG scale.
PBW
Measures PBW (noise power bandwidth) at a resolution band-
width range of 1 kHz to 3 MHz and calibrates it.
(The resolution bandwidth is 30 Hz or more when the narrow-
band RBW option is installed.)
Freq Corr ON/OFF
Toggles the frequency correction function on or off.
ON:
Frequency characteristics are corrected.
OFF:
Turns the frequency correction function off.
Cal Corr ON/OFF
Toggles the calibration factor on or off.
ON:
The calibration factor is used.
OFF:
The calibration factor is not used.
Cal Sig Level
Sets the output level of calibration signals.
1/2_more
Displays the Cal menu (2/2).
Cal 10MHz Ref
Displays the Cal Ref menu.
Coarse
Enters the compensation value for the 10 MHz reference coarse
adjustment.
