To measure channel-to-channel delay
Channel-to-channel delay is the time between a particular event on one
channel and another event on another channel. For example, you might use
this measurement to check skew between two signals in your circuit; in this
case, you would measure the time between the same event occurring on each
channel.
1
Press
Dual Channel
.
2
Press the
Ch Delay
softkey.
3
Press the leftmost
Channel
softkey to highlight the start channel.
The start channel is the reference point for the delay measurement. That is,
the delay time is the time between the first transition on the start channel
and the first transition on the end channel. (Each transition must meet the
rising- or falling-edge specification as defined by the setup.)
4
Select the start channel by using the Entry knob or Select knob, or by
repeatedly pressing the leftmost
Channel
softkey.
5
Select whether the measurement should be referenced to the rising
or falling edge of the start signal by pressing the leftmost
Edge
softkey to highlight the rising or falling edge symbol.
6
Press the rightmost
Channel
softkey to highlight the end channel.
The end channel is the channel for which you want to measure delay time.
7
Select the end channel by using the Entry knob or Select knob, or by
repeatedly pressing the rightmost
Channel
softkey.
8
Select whether the measurement should be referenced to the rising
or falling edge of the end signal by pressing the leftmost
Edge
softkey
to highlight the positive or negative edge symbol.
You must select the desired channels and clock edge before pressing the
Measure Chan Delay
softkey to start the measurement in the next step.
