Input sequencer
Analog, digital, and counter inputs can be scanned based on either an internal programmable timer or an
external clock source.
Table 5. Input sequencer specifications
Scan clock sources: two (Note
3Error! Reference source not
found.)
Internal:
Analog channels from 1 µs to 1 sec in 20.83 ns steps.
Digital channels and counters from 83.33 ns to 1 sec in 20.83 ns steps.
External. TTL-level input:
Analog channels down to 1 µs minimum
Digital channels and counters down to 83 ns minimum
Programmable parameters per scan
Programmable channels (random order)
Programmable gain
Depth 512 locations
Onboard channel-to-channel scan
rate
Analog: 1 MHz maximum
Digital: 12 MHz
External acquisition scan clock
input maximum rate
1.0 MHz
Clock signal range: Logical zero: 0 V to 0.8 V
Logical one: 2.4 V to 5.0 V
Minimum pulse width 50 ns high, 50 ns low
Note 3: The maximum scan clock rate is the inverse of the minimum scan period. The minimum scan period
is equal to 1 µs times the number of analog channels. If a scan contains only digital channels then
the minimum scan period is 83 ns times the number of digital channels.
