Logarithmic and Linear.

Polar/Smith Chart Graticule

± 500 deg in 0.001 deg increments

Noise Averaging

Type

Exponentially weighted vector averaging on successive sweep data

Averaging Factor

Selectable 1 (off), 4, 8, 16, 32, 64, 128, 256

Linear Phase Slope
Compensation

Provides linear phase slope offset of -72,000 deg/span to +72,000
deg/span

Calibration

Transmission

Both traces can be normalized to measured data with full accuracy
and resolution.

Reflection

Corrects for directivity, frequency response and source match
errors

PROGRAMMING CHARACTERISTICS

Capability

Remote programming via the Hewlett-Packard Interface Bus (HP-
IB). The HP 3677A/B S-Parameter Test Sets are programmable
through the HP 3577A interface only.

Interface Functions

SH1, AH1, T5, TE0, L4, LE0, SR1, RL1, PP1, DC1, DT1, C0, E1

Output Data Transfer Time

401 data points (single parameter) can be transferred directly to an
HP 200 series computer in Basic language as follows:
ASCII mode: Typically 1500 ms
Binary-floating point mode: Typically 160 ms

Graphics Capabilities

12 lines of text with 40 alphanumeric characters per line, and high
resolution line vectors can be displayed through HP-IB commands
