MEASUREMENTS
AND ANALYSIS
The WP02 Spectrum Analysis Firmware Package brings powerful FFT
routines to extend the capabilities of the 9400A Digital Oscilloscope into
frequency domain measurement and analysis. It is available as an option,
or may be retrofitted.
The LeCroy 9400A provides 175 MHz bandwidth, 100 megasamples/sec
8-bit ADCs, +2% DC accuracy (+__1% optional), 32K memory per channel,
and up to 192K of waveform storage memory. It is fully programmable over
RS-232-C or optional GPIB interfaces. Plotter drivers enable color archiving
via a wide range of digital plotters.
