These are denoted as “typical,” “nominal,” or “approximate.”

HP 8757D/E scalar network analyzers

The HP 8757D has four independent display channels that process the signals from the HP 85037 series precision detectors (HP 8757D only), the HP 85025 and 85026 detectors, and the HP 85027 series directional bridges for logarithmic display, in single channel or ratio mode. Three (optionally four) detector inputs are provided. The HP 8757E has two independent display channels and three detector inputs.

Display

Horizontal resolution

The number of points (horizontal resolution) that can be selected depends on the number of traces displayed.

Network Analyzer Traces Selectable Number of Points HP 8757E 1, 2 101, 201, 401 HP 8757D 1 101, 201, 401, 801, 1601

2 101, 201, 401, 801 3, 4 101, 201, 401

Display modes

All analyzer display channels can display any one of the detector inputs or any ratio combination of detector inputs.

Log magnitude

dBm: single channel power measurement. dB: relative power measurement (ratio or relative to trace memory).

SWR

Relative measurements (normalized or ratio measurements) can be displayed in SWR. Channels 1 and 2 only: 401 points or fewer.

AUX voltage

The rear panel BNC input ADC IN can be measured and displayed in volts (–10 to +10 volts). Typical maximum error is 60 mV.

Color settings (HP 8757D only)

Up to 8 operator-selectable colors are available for CRT attributes, such as the grid, measurement traces, and labels.

Sweep time

The minimum sweep time depends on the number of traces displayed and the number of points selected.

Number Minimum sweep time (ms) of (log magnitude format) points 1 trace 2 traces 3 traces 4 traces

101 40 50 60 70 201 50 75 90 100 401 100 100 150 200 801 200 250 NA NA 1601 400 NA NA NA

Averaging

2, 4, 8, 16, 32, 64, 128, or 256 successive traces can be averaged.

Smoothing

Provides a linear moving average of adjacent data points. The smoothing aperture defines the trace width (number of data points) to be averaged, and ranges from

0.1% to 20% of the trace width.

Normalization

Traces are stored and normalized with the highest resolution, independent of display scale/division or offset. With adaptive normalization on the HP 8757D, calibration data is interpolated when the frequency span is decreased.

Limit lines (HP 8757D only)

Limit lines facilitate quick pass/fail decisions. Limits can be any combination of flat or sloped lines or single points up to 12 segments. They are only available for channels 1 and 2, for traces with 401 points or fewer, and can be stored in save/recall registers 1 through 4.

Internal save/recall registers

Up to 9 complete front panel states may be saved or recalled. If the source (HP 8360 or 8370 series) is connected to the HP 8757 system interface, the front panel states of both the network analyzer and source are saved. Registers 1 through 4 store the instrument state and the memory traces for channels 1 and 2. The memory traces for channels 3 and 4 are not stored. Registers 5 through 9 only store the instrument state.

System accuracy

T ransmission measurement accuracy

Transmission loss or gain measurements are made rela tive to a 0 dB reference point established at calibration.

Transmission measurement uncertainty

= dynamic power accuracy + mismatch uncertainty

Dynamic power accuracy is the measurement uncertainty due to the change in power level between calibration and the measurement. Mismatch uncertainty is the uncertainty due to reflections in the measurement setup. The frequency response errors of the source, detectors, bridge, and power splitter are removed via calibration.

Transmission measurement uncertainty examples

Assumptions:

• Measurement frequency = 10 GHz

• DUT input/output SWR = 1.5

• Ratio measurement

Precision detector vs. power sensor absolute power measurement accuracy

Accuracy terms differ depending on the test equipment used to make absolute power measurements.

Total (±dB) 0.47 0.30

Reflection measurement accuracy

Uncertainties due to calibration error and the frequency response of the source, detectors, and bridges are removed via open/short averaging. The remaining uncertainties are primarily the sum of directivity uncertainty, effective source match uncertainty, and dynamic power accuracy. As shown in the graphs below, directivity is the dominant error term when measuring small reflected signals (high return loss) and source match is dominant when measuring large reflected signals (low return loss).

Effective source match versus reflection uncertainty

Directivity versus reflection uncertainty

Example calculation

The following example shows how to find the uncertainty (excluding dynamic accuracy), in measuring a 14-dB return loss (SWR = 1.5) with an HP 85027A directional bridge at 10 GHz (directivity = 40 dB, test port match =

1.25 SWR).

Uncertainty Component Uncertainty

Source match error approximately ±0.2 dB Directivity error approximately ±0.4 dB

Total uncertainty approximately ±0.6 dB

Detectors

HP 85037 series precision detectors (AC/DC)

The HP 85037 series precision detectors are designed specifically for operation with the HP 8757D scalar network analyzer and are not compatible with the HP 8757A/E, 8756, or 8755 scalar network analyzers. These detectors may be used in either AC or DC detection modes. For improved power measurement accuracy versus frequency, each HP 85037 series precision detector includes detector specific frequency response data, stored in an internal EEPROM, which is automatically read by the HP 8757D. When used in conjunction with the HP 8757D’s internal power calibrator (Option 002), these detectors provide the maximum absolute power measurement accuracy.

HP 85025 and 85026 series detectors (AC/DC)

The HP 85025 and 85026 series detectors are designed specifically for operation with the HP 8757 scalar network analyzer and are not compatible with either the HP 8756 or the 8755. The HP 85025/26 detectors may be used in either AC or DC detection modes.
