DATA ACQUISITION
PROBE
INTRODUCTION
The P6460 is a 100 MHz data acquisition probe suitable for
use with the 1240/
Acquisition Cards and the DAS
Acquisition Modules. The P6460 has nine data channels and
a clock line. When used with the DAS, one
channels serves as a clock qualifier.
The P6460 probe can also be used with the following DAS
modules:
91
S 16/32 Pattern Generation Module
92A 16/16E Data Acquisition Module
92S 16/32 Pattern Generation Module
