depending on version: single fixed range +/-100mV to +/-14V, bipolar
Note, that approx. 1V of overrange is provided in some devices, e.g. a +/-14V
device actually delivers (at low output current) up to +/-15V
Number of Outputs
1, 2, 4, 8, 10, 12 or 16 output lines, depending on device configuration
Output Connectors
BNC sockets (standard), SubD 25pole female, others on request
Output

Output
Reference Ground
All outputs share a common GND, which can be floated up to +/-100V vs.
case ground.
Output resistance
50 Ohm +/-3% , at I < 2mA, versions +/-5V to +/-14V
2 Ohm +/-15% , at I < 6mA, version +/-100mV
