Freq
Center Freq: Press to set the frequency that you desire to measure to be in
the center of the sweep window. Enter the desired frequency by using the
keypad, the arrow keys, or the rotary knob. If entering a frequency by using
the keypad, then the submenu key labels change to GHz, MHz, kHz, and Hz.
Press the appropriate units key. Pressing the
Enter key has the same effect
as pressing the MHz submenu key.
Span: Press to open the Span menu ( “RF Span Menu” on page 7-13 ). The
Span menu is used to set the frequency range over which the instrument will
sweep. The span can be set from 10 Hz to the maximum frequency range the
product will support. See the product specifications for the maximum
frequency. Span can also be set to zero span.
Freq Step: Press to set to enter the desired frequency step size. The
frequency step specifies the amount by which a frequency will change when
the up or down arrow keys are pressed. The center frequency value can be
changed by using Freq Step. The active parameter will be changed by the
frequency step when the up or down arrow keys are pressed. If Freq Step is
the active parameter, nothing happens when the arrow keys are pressed. The
frequency step size can be any value from 1 Hz to the upper limit of the
instrument with a resolution of 1 Hz. Use the keypad or the rotary knob to
change the Frequency Step size.
Signal Standard: Press to select a signal standard from the list of available
standards. You can edit this list of Signal Standards by using Master Software
Tools. Use the rotary knob or the arrow keys to scroll to the desired standard,
and then press the
Enter key. Or press the Esc key to abort and exit without
a change. Refer to the “(Signal) Standard List Menu” on page 7-14 .
Channel: Press the up or down arrow keys, the keypad, or the rotary knob to
select a channel number for the selected signal standard. The center of the
channel is tuned to the center of the spectrum analyzer display.

submenu key
Set Carrier Freq To Center: Press to set the carrier frequency to the center
of the sweep window. If Demod Type is set to FM or PM, then the
Set Carrier Freq to Center function aligns the carrier to center only if the
carrier is within the IFBW from the center frequency.
