1.Relative to -5 dBm output power for the HP 8753ET; -10 dBm output power for HP 8753ET with Option 004.

2.16 MHz to 3 GHz.

3.16 MHz to 2 GHz.

4.Typical performance.

5.25˚ C ±5˚ C.

6.The HP 8753ET 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.
