R3132 Series Spectrum Analyzer Operation Manual
3.3.9 FREQ Key (Frequency)
3-37
The Start and Stop keys are used to set frequencies.
To set sequential channels which all have the same
channel bandwidth, use the channel numbers in the ap-
propriate table created from the expression in the CH
Type 1 Edit function.
CH Type 2:
Sets the input type to CH Type 2 mode which allows
you to set the
FREQ
, Center, Start and Stop keys using
a channel number.
To set sequential channels which have unique channel
bandwidths, use the channel numbers in the appropriate
table created from the frequency list in the CH Type 2
Edit function.
Start CH Shift Used to enter the shift amount of the start channel’s start frequen-
cy when Input Type is CH Type 2. Sets the start frequency of the
top channel in the CH Type 2 Edit table so that the start frequency
is increased by the shift amount.
Stop CH Shift Used to enter the shift amount of the stop channel’s stop frequen-
cy when Input Type is CH Type 2. Set the stop frequency of the
last channel in the CH Type 2 Edit table so that the stop frequency
is decreased by the shift amount.
CH Type 1 Edit Displays the CH Type 1 Setting editor.
Table 1 to 3 Toggles the table mode (for Table 1 thru 3) between ENABLE
and DISABLE.
ENABLE:
Displays the corresponding table.
DISABLE:
Does not display the corresponding table.
Channel Allows you to edit the channel range.
Enter the start and stop channel numbers so that they satisfy the
following expression:
(Start channel number)≤N≤(Stop channel number).
Carrier Allows you to edit the carrier frequency range.
Enter the value calculated from the following formula:
(Channel spacing)×(Ν+Channel offset)+(Start frequency)
CH Type 2 Edit Displays the CH2 Edit menu and the CH Type 2 Setting editor.
This item is used to enter the channel number, carrier frequency,
channel start frequency and channel stop frequency. A total of 99
channels can be used.
Insert Line Inserts a line in the cursor position.
