Capabilities Description
Oscilloscope Display
Time Base Range Four samples per screen to 48000 samples per
screen, continuously variable with touch-and-
zoom.
Trigger Sources Channel 1 (A channel)
Channel 2 (B channel)

Trigger Modes
Auto New data is displayed in the absence of an edge
trigger being detected.
Normal New data is displayed only following detection of a
trigger. Trace is erased if no trigger occurs.
Trigger Slope Rising or falling edge
Trigger Level Adjustable
Trigger Position The trigger may be positioned anywhere in the
digitized record, with all samples valid. Pretrigger
samples and post-trigger samples must fit within
one record. Trigger position is determined auto-
matically from the views being displayed. There is
no direct control for selecting trigger position in the
record.
Trigger position is at the 0 horizontal graticule
marking.
Cursors Cursors can measure time difference and level
difference on a waveform. Cursor position differ-
ence for both amplitude and time is displayed in
the cursor readout line above the view. Position
difference is obtained by subtracting the readings
obtained from cursor 2 (the dashed cursor) from
the readings obtained from cursor 1 (the solid
cursor). The time reading of the cursor position
displayed above the cursor is with respect to the
trigger point in the waveform.
Listen Capability
LISTEN User may listen to input channels.
