Frequency Settling Time

Table 100. Frequency Settling Time (µs), Typical

PXIe-5842 VST (4 GHz BW)
To ≤1.0 × 10-6 of final frequency ≤230
To ≤0.1 × 10-6 of final frequency ≤250
Frequency settling refers to the time it takes the frequency to settle once the hardware receives the frequency change. The additional time due to software-initiated frequency changes is not included and varies by computer. Frequency settling time includes only frequency settling and excludes any residual amplitude settling.

Phase Settling

Table 101. Phase Settling Time

PXIe-5842 VST (4 GHz BW)
From any band to band 4 1,500 ms
From any band to band 1, 2, 3, or 5 350 ms
If phase settling of one degree is required when changing frequencies, additional settling time must be added when transitioning between upconverter/downconverter center frequency bands.

Band definitions for upconverter/downconverter center frequency:

  • Band 1—Not available
  • Band 2—>1.75 GHz to 7.2 GHz
  • Band 3—>7.2 GHz to 14.4 GHz
  • Band 4—>14.4 GHz to 18.4 GHz
  • Band 5—>18.4 GHz to 26.5 GHz
