Specification
External trigger source input. Requires TTL level input signal. Triggers
on negative edge. Response time 80 - 100 s.
Logic output, active low. Pulse width > 400 s. Function strobe is
generated on any voltage or frequency program change or output relay
open/close. (Mutually exclusive with Trigger Out.)
Logic output, active low. Pulse width > 400 s. Trigger out is generated
based on user programmed transient trigger list. (Mutually exclusive with
Function Strobe.)
16 complete instrument setups and transient lists, 100 events per list.
50 User defined waveforms.
i Series:
Sine.
iX Series:
Sine, square, clipped, user defined (50 waveforms)
Voltage: drop, step, sag, surge, sweep
Frequency: step, sag, surge, sweep
Voltage and Frequency: step, sweep
Two selectable modes of operation:
1.
Constant current mode (voltage folds back with automatic recovery)
2.
Constant voltage mode with output relay trip-off (Output relay
opens).
Note: Only one of the serial interfaces (USB, RS232 or LAN) can be
active at the same time. (Mutually exclusive).
Standard USB 2.0 peripheral.
Data transfer rate: 460,800 bps
Syntax: SCPI
Note:
Use of the USB port to control more than one power
source from a single PC is not recommended, as communication
may not be reliable. Use GPIB interface for multiple power source
control.
Standard RS232 interface.
Data transfer rate: 9600 to 115,200 bps
Format: 8 data, 1 start, 1 stop, no parity.
Syntax: SCPI
AH1, DC1, DT1, L3, RL2, SH1, SR1, T6
IEEE 488.2 and SCPI
Response time is 10 ms (typical)
(Requires –GPIB option on 2253i)
RJ45 Connector, 10BaseT, 100BaseT or 1000BaseT,
Data transfer rate: 460,800 bps
Protocol: TCP/IP.
(-LAN Option on 2253iX only. RS232 interface is disabled with –LAN
option)
