3-10 Freq (Frequency) Menu
Key Sequence:
Freq
The tuning frequency range can be entered in several different ways depending upon what
makes the most sense for the user or for the application. The center frequency and span can
be specified, the start and stop frequencies can be entered, or a signal standard and channel
number can be selected from the built-in list.
Center Freq: Press the Freq main menu key followed by the Center Freq
submenu key and enter the desired frequency using the keypad, the arrow
keys, or the rotary knob. If entering a frequency using the keypad, 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 the MHz
submenu key.
Note: When using the up and down arrows, the frequency moves in steps
defined by the value entered using the Freq Step submenu key. When using
the left or right arrow keys, the frequency of the active parameter moves by
10% of the current frequency span. If the instrument is in zero span, the left
and right arrows do nothing. Turning the rotary knob changes the active
frequency parameter in increments of one display point for each click of the
knob. There are 551 display points across the screen.
Start Freq: Press the Freq main menu key followed by the Start Freq
submenu key and enter the desired frequency using the keypad, the arrow
keys, or the rotary knob. If a start frequency higher than the current stop
frequency is entered, the stop frequency will be changed to yield a
10 Hz span.
Stop Freq: Press the Freq main menu key followed by the Stop Freq
submenu key and enter the desired frequency using the keypad, the arrow
keys, or the rotary knob. If a stop frequency lower than the current start
frequency is entered, the start frequency will be changed to yield a
10 Hz span.
Span: Press the Freq main menu key followed by the Span submenu key
and enter the desired span. 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.
The submenu key shows the current value for span in units of GHz, MHz,
kHz, or Hz. When the Span button is pressed, span becomes the active
parameter and may be changed. Use the keypad, the directional arrow keys,
or the rotary knob to increase or decrease the span frequency. If the span is
changed using the arrow keys, the span changes in 1-2-5 steps for each key
press. See
“Span Menu” on page 3-36 .
