Controller Features
Specification
Trigger Input:
External trigger source input. Requires TTL level input signal. Triggers
on negative edge. Response time 80 - 100
µ
s.
Function Strobe:
Logic output, active low. Pulse width > 400
µ
s. Function strobe is
generated on any voltage or frequency program change or output relay
open/close. (Mutually exclusive with Trigger Out.)
Trigger Out:
Logic output, active low. Pulse width > 400
µ
s. Trigger out is generated
based on user programmed transient trigger list. (Mutually exclusive with
Function Strobe.)
Non volatile memory
storage:
16 complete instrument setups and transient lists, 100 events per list.
50 User defined waveforms.
Waveforms
i Series:
Sine.
iX Series:
Sine, square, clipped, user defined (50 waveforms)
Transients
Voltage: drop, step, sag, surge, sweep
Frequency: step, sag, surge, sweep
Voltage and Frequency: step, sweep
Current Limit Modes:
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).
Control Interfaces
Note: Only one of the serial interfaces (USB, RS232 or LAN) can be
active at the same time. (Mutually exclusive).
USB
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.
RS232
Standard RS232 interface.
Data transfer rate: 9600 to 115,200 bps
Format: 8 data, 1 start, 1 stop, no parity.
Syntax: SCPI
IEEE-488
AH1, DC1, DT1, L3, RL2, SH1, SR1, T6
IEEE 488.2 and SCPI
Response time is 10 ms (typical)
(Requires –GPIB option on 2253i)
LAN / Ethernet
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)
