UCDAS 1602HRS
The CyberResearch brand UCDAS 1602HRS supports the following UDR and UDR Library for .NET
features.
Analog input
Analog input functions and methods supported
UDR:
cbAIn(), cbAInScan(), cbALoadQueue()*, cbFileAInScan(), cbATrig()
UDR for .NET:
AIn(), AInScan(), ALoadQueue()*, FileAInScan(), ATrig()
*The channel-gain queue is limited to 16 elements. The UCDAS 1602HRS accepts
only unique contiguous channels in each element, but the gains may be any valid
value.
Analog input argument values
Options: BACKGROUND, BLOCKIO**, BURSTIO***, CONTINUOUS, EXTTRIGGER, SINGLEIO**, and
EXTCLOCK

SINGLEIO
Equals the number of channels being
sampled.
*** BURSTIO can only be used with the number of samples (Count) set equal to the
size of the FIFO or less. The UCDAS 1602HRS FIFO holds 32,768 samples. Also,
BURSTIO cannot be used with the CONTINUOUS option.
HighChan 0 to 15 in single-ended mode
Count In BURSTIO mode, Count needs to be an integer multiple of the number of channels
in the scan.
 For one-, two- , four-, eight-, and 16-channel scans, the maximum Count is
32768 samples.
 For three- and six-channel scans, the maximum Count is 32766 samples
 For five-channel scans, the maximum Count is 32765 samples
 For seven-channel scans, the maximum Count is 32767 samples
 For 9-, 10-, 12-, 13-, 14-, and 15-channel scans, the maximum Count is
32760 samples
 For 11-channel scans, the maximum Count is 32758 samples.
Rate
: 200 kilohertz (kHz) maximum for BURSTIO mode (50 kHz for any one channel).
For all other modes, the maximum rate per channel depends on the number of
channels being scanned.

When using cbAInScan() or AInScan(), the minimum sample rate is 1 Hz. In
BURSTIO mode, the minimum sample rate is 20 Hz/channel.
