1. Typical performance.
2. Typical below 300 kHz.
3. The Agilent 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 Agilent 8642A/B, 8656B,
or E4432B RF signal generator as the LO source.
4. See the Agilent 8753ES descriptions and options for a functional description.
Measurement accuracy is dependent on the stability of the input signal.
5. Marker resolution for magnitude, phase and delay is dependent upon
measured value. Resolution is limited to five digits.
