4-142 Waterfall Menu
SR785 Dynamic Signal Analyzer
When the measurement is paused, the waterfall is redrawn with either the newest record
at the top (Normal) or reversed (Oldest at Top). If records at the front of the waterfall are
obscuring details ‘hidden’ behind them, reverse the waterfall direction.
Each display has its own Paused Drawing Mode. This entry field can be linked to both
displays by using the [Link] key.
Command: WREV (?) d {, i}
Record to Trace
Save a single record or measurement from the waterfall to a Trace. <Record to Trace>
saves the record selected by the marker to a Trace. Choose a Trace with the knob and
press [Enter] to complete the operation.
A stored trace can be recalled to a Display or Reference Display, used in a User Math
Function, saved to disk, or copied to the Arbitrary Waveform buffer.
When the measurement is paused, use [Alt] knob to move the marker from record to
record (in the Z axis) and scroll the display through the waterfall memory. Use the knob
without [Alt] to move the marker along the X axis within a record.
Command: WTRC (?) d, i, j
Slice to Trace
Save a time ‘slice’ from the waterfall to a Trace. A slice is the history of a single X
position (data at the marker X position from all stored records). Choose a Trace with the
knob and press [Enter] to complete the operation.
The stored slice contains as many points as were stored in the Waterfall buffer (up to
Total Count). The points in a slice trace are numbered and displayed from 0 (data from
oldest record) to n (data from newest record). Note that this differs from the waterfall
display in which the newest record is numbered 0. A recalled slice resemble a time
record (X axis is time advancing left to right) with the X axis labeled as waterfall record
number (instead of time).
A stored slice trace can be recalled to a Display or Reference Display, used in a User
Math Function or saved to disk. A slice can not be copied to the Arbitrary Waveform
buffer.
Command: WSLC (?) d, i, j
