Help with HP 4155 Parameter Analyser

[p1ralad]

Hi everyone... 🙂

I am a master's student and have never worked with LabVIEW.. I have been allotted a HP4155B parameter analyser to measure sweep of Characteristic tests on a FET... I have no idea what and where to look for in order to do so.. I have been provided some specific SubVIs but they are just too complex to study... Would be helpful if someone couls either help me learn or teach me ... I am allowed to share the SubVIs if needed to explain some particular concept ..

Thanks 🙂

P1ralad,

You are in luck as the Keysight (Formerly Agilent/HP) 4155B instrument has a programmer's manual available here. Login and then download the manual from Keysight to understand the SCPI commands that are associated with the manual button control.

Most of the programming is shown in Basic ==> OUTPUT @Hp415x;"*RST"

This is the equivalent of the following in LabVIEW {Setup Instrument in NI-Automation Explorer (NI-MAX) for actual VISA Resource Name}

It really doesn't matter the interface controlling the instrument if it is using the GPIB, Serial (RS-232), or even USB for newer instruments as the control will be the same.  

Just open NI-MAX and then double-click on the Devices and Interfaces selection in the left panel. It should find the instrument and the name of the VISA Resource will be found in the double quotes.

Programming the Hp4155 can be frustrating.  Its an old instrument, and it needs to receive commands in the same order as the pages used to setup a measurement manually.  So, as pointed out by Minions, read the manual and study the examples. Then look at the NI LabVIEW driver with some pre-built examples - https://forums.ni.com/t5/user/viewprofilepage/user-id/111582

After that, post your code attempts and we can help clean them up.
