This data sheet provides two types of performance information:

• System Specifications

• Supplemental Characteristics

System specifications describe the instrument’s warranted performance over the temperature range of 23 °C ± 3 °C (except where noted).

Supplemental characteristics describe the instrument’s non-warranted performance parameters.

System dynamic range

These specifications apply to transmission measurements in the full frequency range at 10 Hz IF BW with response and isolation correction or full two-port calibration. Dynamic range is limited by maximum receiver input level and the receiver’s noise floor.

Measurement uncertainty

Curves show the worst-case magnitude and phase uncertainty for reflection and transmission measurements, after calibration. Calibration is the process of measuring known standards from a calibration kit to characterize a network analyzer’s systematic (repeatable) errors.

Reflection measurement uncertainty is plotted as a function of S11(reflection coefficient). Based on a one-port calibration, using specified calibration kit, with 10 Hz IF bandwidth and no averaging. Assumes a one-port device (S21=S12=0).

Transmission measurement uncertainty is plotted as a function of S21(transmission gain/loss, in dB from reference level). Assumes a well-matched device (S11=S22=0). Based on a full two-port ShortOpen-Load-Thru calibration (including isolation with averaging factor of 8), using specified calibration kit, with 10 Hz IF bandwidth and no averaging.

Measurement port characteristics

The characteristics indicate performance after error-correction (full two-port calibration). The performance accuracy is determined by the quality of calibration standards and how well “known” they are, plus system repeatability, stability, and noise. Crosstalk is not shown, since isolation calibration will reduce crosstalk to the noise floor.

Agilent 8719D, 8720D, 8722D Option 007 Agilent 8719D, 8720D, 8722D Option 085

Includes instruments with Options 012 and/or 089

Option 007 replaces the standard solid-state transfer switch with a mechanical switch to provide higher output power.

Option 085 adds internally controlled 0 to 55 dB step attenuators (5 dB steps) in the receiver path of both ports, an RF loop that allows the addition of an amplifier before the transfer switch, and RF loops after the switch that allow insertion of isolators, required for measurements above 1 watt. An internal reference channel switch is added and internal bias tees are deleted. This system is capable of full two-port calibrated measurements to 20 watts. Measurements up to 100 watts may be possible using specific configurations. Option 085 is not compatible with Option 400.
