Specifications and Characteristics
Operating Characteristics
Split display operation A time-domain waveform and its FFT
spectrum can be displayed simultaneously on the top and bottom halves
of the screen. Four FFT spectra can be displayed simultaneously in the
same way. Four sets of time-domain waveforms and their spectra may
also be displayed simultaneously.
Log Display Sensitivity and offset can be set by the user.
The oscilloscope contains four, nonvolatile waveform memories, two volatile
pixel memories, and 665 multiple failure memories. The four nonvolatile
memories can store four waveforms up to 82K each. The 665 multiple failure
memories store 500 point records. Waveform memories store single-valued
waveforms, such as an averaged waveform. If an envelope waveform is
stored to a waveform memory, it is automatically stored with the upper
waveform in one waveform memory and the lower waveform in another. You
can perform automatic measurements on the four nonvolatile waveform
memories but not the volatile pixel memories.
Waveform memory pairs m1/m2 and m3/m4 also store the upper and lower
limit masks used during compare testing. You can create and edit these
masks using sample signals, or you can create them manually.
Pixel memories store an entire screen of waveform data. Use them for
storing multiple overlapping waveforms and infinite persistence waveforms.
Multiple memories store failure data from limit and compare tests. You can
view or transfer this data to the waveform memory for nonvolatile storage or
measurement.
Waveform and pixel memories can be saved to the disk drive (Disk menu).
