1. FREQUENCY
The RF output frequency range for each model is shown in the following table. When
making frequency changes, the instrument does not turn off the RF output. However, the
power does blank for a few milliseconds when crossing the frequencies at 249, 501, 1001,
1260, 1600, 2001, 2520, and 3200 MHz.
Frequency switching typically takes less than 75 ms at frequencies lower then 1001 MHz,
and less than 100 ms at higher frequencies.
Model Frequency Range
8648A 100 kHz to 1000 MHz
8648B 9 kHz to 2000 MHz
8648C 9 kHz to 3200 MHz
8648D 9 kHz to 4000 MHz
