Specifications Category Specifications
Host Interfaces Computer control interfaces
IEEE-488
IEEE-488.1 compliant. Supports IEEE-488.2 common commands
and status model topology
RS-232
Baud rates from 300bps to 115200bps. Programmable number of
data bits, parity type, and flow control (RTS/CTS hardware or
none). When not programmed as the active host interface, the
SourceMeter can use the RS-232 interface to control other –
instrumentation
Expansion Interface
The TSP-Link expansion interface allows TSP enabled
instruments to trigger and communicate with each other.
Cable Type Category 5e or higher LAN crossover cable
Length 3 meters maximum between each TSP enabled instrument
Digital I/O Interface See 2601/02 GENERAL specifications for circuit diagram

5V Power Supply Pin Limited to 600 mA, solid state fuse protected
Safety Interlock Pin
Active high input. > 3.4 V @ 24 mA (absolute maximum of 6 V)
must be externally applied to this pin to insure 200 V operation.
This signal is pulled down to chassis ground with a 10 K resistor.
200 V operation will be blocked when the INTERLOCK signal is
<_0.4 V (absolute minimum –0.4 V). See figure below:
