Digital Trigger (Digital channels are only available on the 54830/31/32/33D oscilloscopes)
Display
Threshold Range (User Defined) ±8.0 V in 10 mV increments
Threshold Accuracy* ±(100 mV + 3% of threshold setting)
Predefined Thresholds TTL = 1.4 V, 5.0 V CMOS = 2.5 V, 3.3 V CMOS = 1.65 V, 2.5 V CMOS - 1.25 V,
ECL = -1.3 V, PECL - 3.7 V
Trigger Modes Edge
Glitch Select positive or negative polarity,
width. Triggers on glitches as narrow as
5 ns.
Pattern/State Select inputs as High, Low or X (don't
care) to create pattern. Triggers on
patterns as narrow as 2.5 ns.
For State, select logic type of AND or
NAND. Setup time is 2 ns and hold time
is 1 ns.
Delay by Time Time: 5 ns to 10 ms. The trigger is
qualified by an edge. After the delay, a
rising/falling edge on any one selected
input will generate the trigger.
Delay by Events Events: 1 to 16,000,000 rising or falling
edges. The trigger is qualified by an
edge. After the delay, a rising/falling
edge on any one selected input will
generate the trigger.
Pulse Width Triggers on pulse Width >t or Width <t.
Triggers on pulse as narrow as 2.5 ns.
Display 8.4-inch diagonal color active matrix LCD module incorporating amorphous
silicon TFTs. Bus mode for D models.
Annotation Up to 12 annotations, with up to 100 characters each, can be inserted in the
waveform viewing area. Annotations can be saved to and recalled from image
files and setup files.
Display Resolution 640 pixels horizontally x 480 pixels vertically
Dual Intensity Infinite Persistence Previous sweeps are stored in half bright display and most recent sweep in full
bright. This allows easy differentiation of current and historic information.
Waveform Overlap When two waveforms overlap, a third color distinguishes the overlap area.
Full screen mode On/Off selectable.
Connect-the-dots On/Off selectable.
Persistence Minimum, Variable (100 ms to 40 s), Infinite. Up to 6 levels of grey scale.
Graticule On/Off
Grid Intensity 0 to 100%
Waveforms/sec >3,100
Vpp Measurements/sec >190
Deep Memory Display Update Rate
(8 MPts)
Waveforms/sec >50
