Some helpful tips
Performing a time-base calibration
A N9340A provides a manual calibration function
to calibrate the time base.
Before calibration, allow the analyzer to warm up
for about 30 minutes.
Use a BNC cable to connect a 10 MHz reference
signal to the
EXT TRIG IN connector of your N9340A,
then press
[SYS] > {More (2 of 3)} > {Calibration} > {Time
Base} to initiate a calibration.
Selecting a preset type
The analyzer has two types of preset setting for
you to choose:
• Default
Restores the analyzer to its factory- defined
setting.
• User
Restores the analyzer to a user- defined setting.
How to Save a User-defined Preset
If you constantly use system setting which is not
the factory default, please refer to the following
steps to create a user- defined system setting:
1 Set analyzer parameters by the knob, the arrow
keys or the numeric keypad.
2 Press [SYS] > {More (1 of 3)} > {Preset} > {Save User}
to save the current parameters as the user
preset setting.
3 Press [SYS] > {More (1 of 3)} > {Preset} (User) to set
the preset mode to user defined system setting.
NOTE
Powering on the instrument always brings up a
factory-defined setting no matter the Preset setting.
