LO frequency accuracy9

±1 MHz at nominal frequency

1.Relative to 0 dBm output power.

3.16 MHz to 3 GHz.

4.16 MHz to 2 GHz.

5.Typical from 2 to 3 GHz for instruments with Option 075.

6.+8 dBm maximum with Option 075, or Option 014.

7.Test performed on port 1 only.

8.Instruments with Option 075 are degraded 2 dB.

9.Typical performance.

10.25˚ ±5˚ C.

11.The HP 8753ES source characteristics and measurement accuracy in this mode are dependent on the stability of the external LO source. The RF source tracks the LO to maintain a stable IF signal at the R-channel receiver input. Degradation in accuracy is negligible when using an HP 8642A/B, 8656B, or E4432B RF signal generator as the LO source.
