Entering and Changing Numbers
To Change the Increment or Decrement Setting
Using the Pre-Defined Increment/Decrement Keys
The INCR
×10]
and INCR
÷10]
keys change the increment/decrement value by a
factor of 10.
For example; if the
Tune Freq
presently changes by 10 MHz for every click of
the knob or push of the down-arrow or up-arrow keys, pushing INCR
×10]
once
changes the increment value to 100 MHz.
Specifying An Increment Value
The INCR SET key is used to assign a specific increment value. The increment
value may use different units than the field you are incrementing/decrementing.
For instance; if the RF Generator
Amplitude
setting is displayed in dB
µ
V, you
could increment in units of dB or mV.
To change the increment value;
1. Move the cursor to the numeric entry field to be changed.
2. Press INCR SET, and enter the desired value and unit-of-measure using the DATA
keys.
3. Use the down-arrow and up-arrow keys or CURSOR CONTROL knob to change the
field’s value by the increment value you set.
Example of Setting an Increment Value
This example changes the
Tune Freq
in increments of 15 MHz.
1. Access the TX TEST screen and position the cursor in front of the
Tune Freq
field.
2. Press 1 0 0 MHz to set the frequency at 100 MHz.
3. Press INCR SET 1 5 MHz.
4. Turn the Cursor Control knob. The field’s value changes by 15 MHz for each knob
click.
