11 | Keysight | 89601B/BN-200 Basic Vector Signal Analysis, 89601B/BN-300 Hardware Connectivity, 89600 VSA Software - Technical Overview
Trace data (continued)
For up to 8 channels, each channel displayed individually
Displays ACP or OBW tabular data
Marker
Math
Displays computed data in math register
Channel N x M (where M<N) cross channel data
Coherence
Indicates similarity between two signals
Cross correlation
Cross spectrum
Determines time delays of a common signal between two different paths
Cross power spectrum of ch N vs ch M
Frequency response
Impulse response
Trace math
Frequency response of ch N vs ch M
Inverse of frequency response for ch N vs ch M
Uses
Trace math can be used to manipulate data on each measurement. With multi-measurements, trace
math can be done between results from different measurements. Applications include user-defined
measurement units, data correction, and normalization.
Operands
Measurement data, data register, constants, jw
Operations
+, –, x, /, conjugate, magnitude, phase, real, imaginary, square, square root, FFT, inverse FFT, windowing,
logarithm, exponential, peak value, reciprocal, phase unwrap, zero
Graphs
Perform complex stimulus-response measurements with modulated signals
Graph settings
Stimulus and response data selection (auto or manual)
Compensation (amplitude normalization, time alignment, phase error compensation)
Polynomial order of curve-fit line
Graph results
Differential error vector magnitude, averaged over all time points
Average gain of response data over stimulus data
Delay between stimulus and response data
Average stimulus power
Average response power
Coefficients for curve-fit line
Trace appearance
Trace formats
Log mag (dB or linear), linear mag, real (I), real (Q), wrap phase, unwrap phase, I-Q, constellation, I-eye,
Q-eye, trellis-eye, group delay
Trace layouts
Unlimited traces, displayed on detachable grids with user-determined layout
User-definable color palette
Number of colors
Special visualization displays
Adjustable parameters
Color mapping
Unique visual tools providing ways of looking at time-varying signals
Color normal, color reverse, grey normal, grey reverse, user-defined
Determines how colors are distributed.
Enhance
Threshold
Sets threshold value for currently selected visualization display type
Cumulative history, digital persistence, spectrogram
Display types
Averaging
Types
RMS (video), RMS (video) exponential, peak hold, time, time exponential
