Test Equipment–Connectors

The following are Connector Transforms:



BK Power Supply

Controls power supplies from BK Precision. See BK Power Supplies.

ICSE GPIB Power Supply

Controls a power supply using an ICS Electronics GPIB Controller.  Tested with a Tektronix PS2521G power supply. Source code is available from Danlaw.

GW Instek PSW Power Supply

Controls a PSW series Programmable Switching Power Supply from GW Instek. See:

GW Instek Power Supply


PI Resistor Card


Controls a Pickering Interfaces resistor card, style 50-295-021.

An example of a use for this Transform is for converting temperature to resistance. Use a Lookup Table transform (C# Snippet or SIL Easy) to convert a temperature stimulus Signal from a test case. Then connect the converted Signal to this Transform to control resistance in the test harness.



The USB RLY08 Transform interfaces with the following USB relay boards manufactured by Devantech Ltd:




The driver for the relay board maps the USB to a COM port. Each board uses a different driver. USB-RLY08 and USB-RLY16 use the FTDI VCP drivers: http://www.ftdichip.com/Drivers/VCP.htm The USB-RLY08B driver and instructions are at http://www.robot-electronics.co.uk/htm/usb_rly08btech.htm.

The USB relay is used in conjunction with the RS232 COM port as shown in the image above. The COM port should be set up for 19200 baud, 8 data-bits, no parity, and two stop-bits.
