Programmable Resistance Decade Box

PRS Series Programmable Resistance Decade Boxes

Full PRS Series Data sheet and specs (.PDF Format)

A broad range of programmable resistance decade boxes for applications requiring a programmable impedance unit, controlled manually and by a computer via an IEEE-488, RS-232 or BCD interface.

  • Wide range and resolution: 1 mΩ to 100 MΩ

  • Avaliable at accuracies of : 0.01%, 0.02%, 0.05%, 0.1%, 0.5%, and 1% Programmable Resistance Decade Box

  • LabVIEW Drivers for IEEE-488.2 and RS-232 Versions

  • Special RTD and custom configurations

  • High power versions avaialable

  • Programmable "open circuit" and "short circuit" states optional

  • Desktop and 19" Rackmount enclosures

  • Dual / Combo rackmount models ( examples: dual resistance, resistance & capacitance )

  • Manual thumbwheel operation or programmable digital input, RS-232 or GPIB (IEEE-488.2 interface)

  • effective programmable impedance unit controlled manually and by a computer

  • Windows tools and IEEE-488 interface software and hardware available

Test Keyboard

To aid the user in operating the PRS/PCS/PLS, Two “Keyboard” Controller programs - the easiest way to control GPIB or RS232 devices without writing a program - are available from IET. This Keyboard programs automatically finds your device at start-up and it lets you enter just the data that you want to send to the device. This program works with ICS, Measurement Computing and National Instruments controllers. 

For GPIB   IEEE-488.1 and IEEE-488.2 interface
Download ICS_GPIBkybd_Install.zip

Unzip the file and follow instructions to install. Open the application.  You may use the Find Listeners button to confirm that the PRS unit is recognized. Other instruments may also be recognized at this time.

Enter and set the Address to the PRS address. Use the window to send a command string to the PRS, where the command string is constructed as described in the operating manual. A command string might be, for example:
SOURce:DATA resistance string

For Serial RS-232 interface:
Download: ICS_Serkybd_Install.zip

Unzip the file and follow instructions to install. Open the application.  Initialize the COM PORT and use the Device Command window to send a command string to the PRS, where the command string is constructed as described in the operating manual. A command string might be, for example:
SOURce:DATA resistance string
