ANALOGUE REMOTE INTERFACE (CPX400SA only)
The CPX400SA offers galvanically isolated analogue remote control of voltage and current
from control voltages. Voltage and current front panel settings generate non-isolated analogue
output voltages that can be used to control slave power supplies.
Input Scaling: 0 to 100% control of voltage or current from 0 to 5V or 0 to 10V
(selectable)
Input Accuracy: Voltage: 0.3% ±20mV. Current: 0.5% ±50mA.
Input impedance 10kW
Output Scaling: Set values of 0 to 100% of rated output voltage and current
generate 0 to 5V (not isolated)
Output Accuracy: Voltage: 0.3% ±20mV. Current: 0.5% ±50mA.
Output impedance 125W
Remote On/Off: Output On/Off can be controlled by external switch closure
(not isolated)
DIGITAL BUS INTERFACES (CPX400SP & CPX400DP only)
The CPX400SP & CPX400DP offers full remote control and read-back using RS-232, USB, GPIB
or LAN (compliant with LXI class C). All interfaces are at ground potential and opto-isolated
from the output terminals. Note: Remote/Local Sense, is manually selectable only.
RS-232
Standard 9-pin D connector. Baud rate 9,600.
USB
USB 2.0 connection (backwards compatible with USB 1.x). Operates as a virtual COM port.
GPIB (IEEE-488)
The interface conforms with IEEE-488.1 and IEEE-488.2.
Ethernet (LAN)
Standard 10/100 base-T hardware connection. ICMP and TCP/IP Protocol for connection to
Local Area Network or direct connection to a single PC.
LXI Compliance
LAN interface is compliant with LXI class C. (LXI is the abbreviation for Lan eXtensions for
Instrumentation). For more information visit: www.tti-test.com/go/lxi
DIGITAL PROGRAMMING PERFORMANCE (CPX400SP & DP only)
Voltage Setting
Resolution/Accuracy: 1mV / ± (0.05% +10mV)
Current Setting
Resolution/Accuracy: 1mA / ± (0.3% +5mA)
Programming Speed
Command Delay: Typically <25ms (this must be added to any of the figures below)
Voltage Up Time: <10ms* to 1%
Voltage Down Time: <80ms* to 1% (full load); <1.5s* to 1% (no load)
* The up and down times vary with range and voltage step size. More information is
contained in the operating manual which can be downloaded from our web site.
