DEMO MANUAL DC1996A

QUICK START PROCEDURE

Demonstration circuit 1996A is easy to set up and evaluate

for performance. Refer to Figure 1 and follow the proce-

dure below.

n

Connect the DC1996A to a DC890 USB high speed data

collection board using edge connector P1.

n

Connect the DC890 to a host PC with a standard USB

A/B cable.

n

Apply a low jitter signal source to J2 to test channel

2, or to J4 to test channel 1. Note that the DC1996A

is capable of accepting a differential input signal as

well as a single-ended signal. See the Hardware Setup

section for the jumper positions that correspond to

these configurations.

n

As a clock source, apply a low jitter 10dBm sine wave or

square wave to connector J1. See Table 1 for maximum

clock frequencies. Note that J1 has a 50Ω termination

resistor to ground.

n

Run the PScope software (Pscope.exe version K73,

or later) supplied with the DC890 or download it from

umentation 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 DC1996A

and configure itself automatically.

n

Click the Collect button (Figure 2) to begin acquiring

data. The Collect button then changes to Pause, which

can be used to stop data acquisition.
