Characteristic Description
Slots 4 C-size, compliant with VXIBus System Spec Rev. 1.4, except as follows:
MODID driver not capable of sinking 48 mA as required for 3-state lines (meets standard
design practices for VXI); and
TTLTRG~ may not be unasserted after SYSRESET~, as ADG332 does not use
SYSRESET~ (accommodated by local controller reset)
n CLK10 Frequency 10 MHz ±100 PPM
Relative time correlation error
(typical)
Typical measured relative time correlation error between modules in the same instrument
Includes typical jitter, slot-to-slot skew, and probe-to-probe variations to provide a simple,
overall, typical value. Assumes standard accessory probes are used.
For long-term (> 1 s) time interval measurements between modules add 0.01% of the delta
time between the absolute time measurements to the relative time correlation error to account
for the inaccuracy of the CLK10 source.

Smpl represents the time from the event to the next valid data sample at the LA probe tip. In the normal internal clock
mode, this represents the delta time to the next sample clock.
2
DSO modules time correlation measured at the maximum sample rate on one channel only
3
During this measurement the DSO is measuring the CLK channel of the LA module. If the DSO measures a data
channel from the time the data edge occurs until the clock edge occurs, the time must be included

The input bandwidth specifications apply only to signals to the modules from the External Signal Input connector, not
to round-trip signals into the External Signal Input connector and back out of the External Signal Output connector.
