Signal Analysis
Waveform Processing
Processing functions: Add,
Subtract, Multiply, Divide, Negate,
Identity, Summation Averaging, and
Sine x/x; four functions performable
at one time
Average: Summed averaging of up to
1000 waveforms in the basic instrument;
up to 10
6
averages possible with optional
WP01 Advanced Waveform Math Package
Extrema: Roof, Floor or Envelope values of from 1 to 10
6
waveforms
— with WP01 Option
ERES: Low-Pass digital filter provides up to 11 bits vertical
resolution; sampled data always available, even when trace
turned off; any of above modes usable without destroying data
— with WP01 Option
FFT: Spectral Analysis with five windowing functions and FFT
averaging, with optional WP02 Spectrum Analysis Package
Histogramming and Trending: With optional WP03 Parameter
Analysis Package, in-depth diagnostics on waveform parameters
Internal Memory
Waveform Memory: Up to four 16-bit Memories.
Processing Memory: Up to four 16-bit Waveform Processing
Memories.
Cursor Measurements
Relative Time: Provides time and voltage differences relative to
each other
Relative Voltage: Measures voltage differences up to ±0.2% of
full-scale
Absolute Time: Measures time relative to trigger and voltage
with respect to ground
Absolute Voltage: Measures voltage with respect to ground
