Definitions and test conditions

Specifications describe the instrument's warranted performance after a half-hour warm-up and over the temperature range of 25 ˚C ± 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 non-war- ranted performance parameters. These are denoted as “typical,” “nominal,” or “approximate.”

The measurement uncertainty curves and measure- ment port characteristics given for HP 8753ES systems also apply to the HP 8753ES with Options 006 and 011 and the HP 85047A test set (50-ohm), or the HP 8753ES Option 011 with an HP 85046B test set (75-ohm).

Dynamic range

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 mea- surements 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 correc- tion for the HP 8753ES and enhanced-response error correction for the HP 8753ET (with 16 averages used during isolation), 10 Hz IF bandwidth (BW), maximum test port power, and no averaging during the measure- ment.

Measurement uncertainty

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 measure- ments, after a full two-port error correction for the HP 8753ES and enhanced-response error correction for the HP 8753ET (including isolation with an averag- ing factor of 16) using the specified cal kit, with 10 Hz IF bandwidth (BW) and no averaging.

Measurement port characteristics

Characteristics show the residual system uncertainties for uncorrected performance and after accuracy enhancement using full two-port error correction for the HP 8753ES and enhanced-response error correc- tion for the HP 8753ET. These characteristics apply for an environmental temperature of 25 ± 5 ˚C, with less than 1 ˚C deviation from the calibration tempera- ture. HP 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 calibra- tion 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.
