Prerequisites

Warm-up time: 30 minutes

Digital timing generator

setup

1.

Verify that the digital timing generator (DTG) has been calibrated so that the
channel-to-channel skew is minimized.

2.

Set up the DTG so that a channel (CH1 for example), is set to be a clock
pattern of alternating 1 and 0 (101010… binary) starting with 1 (rising edge).

3.

Set the output frequency to 250 MHz. (This may require you to set the DTG
base clock to 500 MHz for this pattern to represent 250 MHz at the channel
output.)

4.

Set another channel of the DTG (CH2 for example) to a data pattern
representing half the period of CH1 (for example 001100110011...binary,
starting with 00).

5.

Connect the setup and hold test

fi

xtures to the DTG channels that you have set

up. Connect 50

Ω

SMA terminations to the test

fi

xtures.

6.

Connect the DTG channel that you set up as a clock to the appropriate TLA
CK[x] input.

7.

Connect the other DTG channel to two of the TLA data channels that you
want to test.

To test other TLA data channels simultaneously and your DTG has additional
outputs available, set up those DTG channels like the

fi

rst data channel, and

connect them to the other logic analyzer channels that you want to test. (The
channels must be in the same probe, and you will need another test

fi

xture

for each additional channel pair.) Otherwise, repeat the procedure for each
new pair of logic analyzer channels.

8.

Set the termination to open on each DTG channel.

9.

Set the DTG output voltage levels to 2.0 V High and 0.0 V Low, with no offset.
