Specifications describe the instrument’s warranted performance after a half-hour warm-up and over the temperature range of 25° ± 5° C, unless otherwise stated. Specifications for frequencies above 3 GHz do not apply to instruments with Option 075 (75-ohm impedance). Supplemental characteristics are typical but nonwarranted performance parameters. These are denoted as “typical,” “nominal,” or “approximate.” The measurement uncertainty curves and measurement port characteristics given for Agilent Technologies 8753ES systems also apply to the 8753ES with Options 006 and 011 and the 85047A test set (50-ohm), or the 8753ES Option 011 with an 85046B test set (75-ohm).

System dynamic range is calculated as the difference between the receiver noise floor and the lesser of either the source maximum output or the receiver maximum input level. System dynamic range applies to transmission measurements only, since reflection measurements are limited by directivity. Noise floor is specified as the mean of the noise trace over frequency. Noise floor is measured with the test ports terminated in loads, full two-port error correction for the 8753ES and enhancedresponse error correction for the 8753ET (with 16 averages used during isolation), 10 Hz IF bandwidth (BW), maximum test port power, and no averaging during the measurement.

Measurement uncertainty curves utilize a Root Sum Square (RSS) model for the contribution of random errors such as noise, typical connector repeatabilities, and test set switching; this is combined with a worst-case model for the contributions of dynamic accuracy and residual systematic errors. Curves show the worst-case magnitude and phase uncertainty for reflection and transmission measurements, after a full two-port error correction for the 8753ES and enhanced-response error correction for the 8753ET (including isolation with an averaging factor of 16) using the specified cal kit, with 10 Hz IF bandwidth (BW) and no averaging.

Characteristics show the residual system uncertainties for uncorrected performance and after accuracy enhancement using full two-port error correction for the 8753ES and enhanced-response error correction for the 8753ET. These characteristics apply for an environmental temperature of 25° ± 5° C, with less than 1° C deviation from the calibration temperature. Agilent 8753ET Option 004 may degrade transmission source match as much as 2 dB, resulting in up to 0.05 dB additional uncertainty in transmission tracking. Corrected performance indicates residual error after calibration. It is determined by the quality of calibration standards, system repeatability, stability, and noise. Uncorrected performance indicates intrinsic errors without calibration correction applied. This is related to the ultimate stability of a calibration.
