Frequency Tuning Times

The PXIe-5654 is a highly agile frequency synthesizer. When the fast tuning option is available, the PXIe-5654 can usually tune to and from any frequency in 100 µs or 150 µs when tuning to frequencies less than 250 MHz.

One exception occurs when the device switches from a higher frequency to a frequency of 250 MHz or less; if a frequency switch crosses the 250 MHz threshold in a high-to-low direction, the frequency settling time increases. The standard switching time without the fast tuning option is 1 ms.

Note Refer to the PXIe-5654 Specifications document for frequency settling times.
