Stimulus duration at
destination temperature
0 – 600 Sec (limited by safety cut-off. See below)
Inter-sequence time interval
(Time interval between
sequences)
0 – 600 Sec., in 0.1 Sec. resolution
Intra-sequence time interval
(Time interval between
stimuli, in one sequence)
0 – 600 Sec., counted onset-to-onset or end-to-onset, in 0.1
Sec. resolution.
Optionally, this interval can be randomized within a
predetermined range.
Randomize Option
Option to randomize between sequences
Number of stimuli in a
program
Each sequence can include up to 100 trials (stimuli). The
number of sequences in a program can be more than 100.
Stimuli trigger options
Automatic
Manual using designated push button or keyboard
External, via a TTL input
Synchronization options
TTL Input
Externally trigger the onset of stimulus
Voltage: ± 5V
Current: 10 – 15 mA
Minimum Duration: 10 msec.
Synchronization options
TTL Output
Can indicate various events during stimuli (depending on
protocol used)
Voltage: ± 5V
Current: 2 mA
Duration: 50 – 1000 msec
Auxiliary TTL output option
TTL output on a predetermined delay after onset. Delay is
programmable. Duration of TTL output is programmable in
the range of 50 to 600 milliseconds. Other characteristics
are same as for TTL Out.
