4-180 Disk Buffers Menu
SR785 Dynamic Signal Analyzer
The waterfall buffers for both displays are saved together (all stored waterfall records for
both displays are saved). If one display has waterfall storage off, then no data is saved
for that display.
Capture and Arbitrary files are compatible. Data saved from a capture buffer can be
loaded into the arbitrary waveform buffer (and vice versa).
Interval
Choose to save the entire data buffer or only the playback portion (Capture or Arbitrary
Waveform). All stored waterfall records for both displays are saved.
This only affects the saving of data to disk. When a buffer is loaded from disk, the buffer
is configured to be exactly the length of the recalled data.
Disk to Buffer
Load binary data from the Current File in the Current Directory into the selected data
buffer. This function only recalls files made using <Buffer to Disk>. The selected buffer
(Capture, Arbitrary Waveform or Waterfall) must have sufficient memory allocated
before loading from disk.
Load Arbitrary Waveform
A saved Arbitrary or Capture file may be loaded into the Arbitrary Waveform buffer.
The Arb. Src. Length will be set to the length of the disk data.
Load A Capture Buffer
A saved Arbitrary or Capture file may be loaded into a Capture buffer.
If the disk data has the same Capture Length and Sampling Rate as shown in the current
[Capture] menu, the data is simply loaded into the selected channel’s buffer. In the case
of Ch1+Ch2 capture, loading one channel does not disturb the contents of the other
channel’s buffer.
If either the length or sampling rate is different from the current [Capture] menu, they are
changed to the length and sampling rate of the disk data. In the case of Ch1+Ch2 capture,
loading Ch1 (Ch2) capture will zero the Ch2 (Ch1) capture buffer if the capture length or
sampling rate is changed by this operation.
To recall both capture channels, configure <Capture Channels> for Ch1+Ch2. Both files
must contain the same length buffers with the same sampling rate. Use <Buffer> to
choose either Ch1 or Ch2 and load the appropriate disk file to the buffer. This will set
the capture length and sampling rate according to the recalled disk file. Then use
<Buffer> to choose the other channel and load the other disk file to the buffer. Since the
existing Capture Length and Sampling Rate are already compatible, this operation does
not zero the first capture buffer.
Load the Waterfall Buffer
A saved Waterfall file may be loaded into the Waterfall buffer.
