How to ? View the analog characteristics of a digital signal
View the analog characteristics of a digital signal
NOTE. iCapture is available only on MSO70000C Series instruments.
The iCapture function allows you to view the analog characteristics of signals connected to a digital
channel. Additional measurement capabilities are available while viewing the analog characteristics of a
signal. You
can route up to four of the 16 digital inputs (D15-D0) and Clock/qualifier inputs to the analog
channels through a logic probe using iCapture. When a logic channel is routed to an analog channel, the
normal signal ( analog input) is no longer visible.
To use iCapture, follow these steps:
1. From the Vertical menu, select Vertical Setup.
2. Press the Digital Input iCapture button.
3. Click the Digital Source box and select a signal connected to a digital channel to send through the
analog input.
4. To set the voltage reference level thresholds of the channel for the instrument to use when converting
an analog waveform to digital format to include in a bus, c lick the Digital Properties button.
5. To choose whether to share threshold settings or to have independent threshold settings, click in the
Channel Settings box, and select Shared or Independent from t he list.
6. For each threshold you want to change, click the channel threshold entry box, and use the keypad or
multipurpose knobs to set the threshold level.
7. Click OK.

NOTE. Acquiring digital s ignals is available only on M SO5000 and MSO70000C Series instruments and
DPO5000 Series instruments with option MSOE installed.
You can set the voltage reference level threshold, position, and display size parameters for digital signal
acquisition. To do so, follow these steps:
1. Connect the logic probe to the input signal source using proper probing and connecting techniques.
2. Click here
(see page 87) for details on setting up the Digital input controls.
