User Manual 3153
Using The Instrument 3-29
measured between the two transition points of the first edge.
The query:
PULSe:TRANsition?
queries the pulse rise time setting and returns a value in percent.
The command:
PULSe:WIDTh <value>
sets the pulse width in percent of the pulse period. For example, if the
pulse period is 100 ms, 20% pulse width equals 20 ms. Pulse width is
measured between the two transition points on the top of the pulse.
The query:
PULSe:WIDTh?
queries the pulse width setting and returns a value in percent.
The command:
PULSe:TRANsition:TRAiling <value>
sets the pulse fall time in percent of the pulse period. For example, if the
pulse period is 100 ms, 15% fall time equals 15 ms. Pulse fall time is
measured between the two transition points of the falling edge.
The query:
PULSe:TRANsition:TRAiling?
queries the pulse fall time setting and returns a value in percent.
Generating Arbitrary
Waveforms
The Model 3153 cannot generate arbitrary waveforms without first
loading them into memory. A description of the arbitrary waveform
function and an explanation of how to load waveforms into memory are
given in the following paragraphs.
What Are Arbitrary
Waveforms?
Arbitrary waveforms are generated from digital data points which are
stored in memory. Each data point has a vertical resolution of 12 bits
(4096 points), i.e., each sample is placed on the vertical axis with a
precision of 1/4096.
The Model 3153 has the following waveform memory capacity:
Channel 1 - 512k standard, 2Meg optional
Channel 2/3 – 2Meg standard, 4 and 8Meg optional
