DEMO MANUAL DC2365A

DC890 QUICK START PROCEDURE

Check to make sure that all switches and jumpers are

set to their default settings as described in the DC2365A

Jumpers section of this manual. The default connections

configuretheADCtousetheonboardreferenceandregula-

tors to generate all the required bias voltages. The analog

inputs by default are DC-coupled. Connect the DC2365A

to a DC890 USB high speed data collection board using

connector P1. Then, connect the DC890 to a host PC with

a standard USB A/B cable. Apply ±16V to the indicated

terminals. Then apply a low jitter signal source to J5 and

J6. Use J7 to route the signal sources of J5 and J6 to the

desired AIN0–AIN7 inputs. Observe the recommended

input voltage range for each analog input. Connect a low

See Table 1 for the appropriate clock frequency. Note that

J1 has a 50Ω termination resistor to ground.

Run the PScope™ software (Pscope.exe version K94 or

later) which can be downloaded from www.linear.com/

designtools/software.

Complete software documentation is available from the

Help menu. Updates can be downloaded from the Tools

menu. Check for updates periodically as new features

may be added.

The PScope software should recognize the DC2365A and

configure itself automatically.

Click the Collect button (Figure 2) to begin acquiring data.

The Collect button then changes to Pause, which can be

clicked to stop data acquisition.
