Entering and Changing Numbers
Entering and Changing Numbers
Values for numeric entry fields can be entered and changed using various
methods, depending on your testing needs. The unit-of-measure for some of these
fields can also be changed (such as changing the RF Generator’s
Amplitude
units from dBm to
µV).
To Enter Numbers
1. Position the cursor in front of the numeric entry field to be changed.
2. Use one of the following methods:
a. enter the number and unit-of-measure directly using the keypad,
or
b. press the Cursor Control knob or ENTER to highlight the field, and use the
knob,
or
c. use the down-arrow or the up-arrow keys to increment or decrement the present
value.
Decimal Values
Decimal values are used for most numeric entry fields, such as the RF Gen Freq
setting. The acceptable entries for decimal values are 0 through 9, ., +/-, and EEX.
The +/- key is used for entering negative numbers. For example; when entering
the RF Generator
Amplitude you can enter this sequence to set the value to
−47 dBm: +/- 4 7 dBm.
The EEX key can be used when entering exponential notation. For example; to
enter 1.25
× 10
3
kHz you could use the sequence: 1 . 2 5 EEX 3 kHz.
