238 HP E1419 Command Reference
•
<time> can be one of 16 possible numeric values or MIN and MAX:
0
1.2 mS
19.2 mS
307.2 mS
Sending 0 or MIN turns debounce off. Sending MAX selects 2.458 seconds.
–
If a value is sent that is slightly greater than one of these values, the next
–
higher value (or MAX) is selected. Values outside of the range 0 - 2.4576 will
generate the error -222, "Data out of range".
•
Since the HP E1536 has two debounce timers (one for each bank of 4 channels)
<ch_list> must contain all 4 of the upper-bank channels, or all 4 of the lower-bank
channels, or all 8 channels for a given SCP. This is because the HP E1536 has two
debounce timers, one for its lower 4 channels and one for its upper 4 channels.
The INP:DEB:TIME generate the error 3108, "E1536 debounce - each referenced 4
Ch bank must contain at least one input". This error indicates that <ch_list>
referenced a bank of channels that contains no input configured channel.
•
Usage: To set the debounce period to 153.6 msec for the lower 4 channels on an
HP E1536A in SCP position 0 send:
INP:DEB 0.1536,(@100:103)
To set the debounce period to 1.229 seconds for the upper 4 channels on an
HP E1536A in SCP position 3 send:
INP:DEB 1.229,(@128:131)
•
There is also the query form; INPut:DEBounce:TIME? (@<channel>)
where <channel> must specify a single channel. INP:DEB:TIME? returns the
currently set debounce period.
INPut:FILTer[:LPASs]:FREQuency <cutoff_freq>,(@<ch_list>) sets the cutoff
frequency of the filter on the specified channels.
