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.
