Test Frequency

Test frequency point
The E4980A/AL's test frequency can be set in the range from 20 Hz to 2 MHz.
The last digit of the four-digit test frequency display (including digits after the
decimal point) can be set as the resolution.
Table 3-7
Table 3-7 Frequency range and test frequency point
Frequency range (F)
20 Hz  F  99.99 Hz
100 Hz  F  999.9 Hz
1 kHz  F  9.999 kHz
10 kHz  F  99.99 kHz
100 kHz  F  999.9 kHz
1 MHz  F  2 MHz
When more than five-digit numeric data (including digits after the decimal
point) are entered, the nearest test frequency point is automatically set.
Procedure for setting test frequency
Step 1. Press the [Display Format] key.
Step 2. Use the cursor keys to select the FREQ field.
Step 3. Use the softkeys or numeric entry keys to enter the test frequency. When
data is entered with the numeric entry keys, the softkeys change to unit
labels (Hz, kHz, MHz).

Function
Increments the test frequency to the next sequentially higher tenfold
value after 20 Hz. Refer to
that can be set using this softkey.
Increments the current test frequency to the next sequentially
higher frequency point. There are ten frequency points between
successive decade values. Refer to
frequency points that can be set using this softkey.
