The Front Panel and the Block Diagram. What does it meant? In any case, does the instrument assert EOI at the end of a transmission? Message 9 of 9. My VI works fine, but I’ve just realized that I need to retrieve not only magnitude, but also phase of the signal. What class is my USB device?

That means talking to the vendor about what functions are in the dll, the parameters for each function, and a description of each function.

Instrument Control (GPIB, Serial, VISA, IVI)

I am sorry a s i am new in this forum and thank you for your fast reply. Message 6 of 9.

The X voltage is done in exactly the same way with the SEN and 6 values averaged with the formula. Yes, lsbview may well be able to help. What I’m trying to ascertain: I try to obtain a frequency response, so I change the frequencies that are sent to the lock-in and to the device under investigation.

Remote Control of SIGNAL RECOVERY Lock in Amplifier Using Labview | Furkan Eris –

Message 14 of What I know is: Then you should try to learn the communication basics as described in the manuals of your devices.


I want to use the GPIB card to interface with labgiew Signal Recovery Lock-in amplifier model which is triggered by a motion controller stage. These functions in the block diagram can be described in 3 ways: The worked with a direct connection to labgiew computer and no USB conversion, getting the device to communicate with the Keithley device proved difficult so instead this was usen.

Since you say you have a dll, you really need to get the api for it. I am unable the modified any setting for the GPIB setting.

Making a Thermocouple Measurement With NI LabVIEW

The front panel of this example allows the user to:. In any case, does the instrument assert EOI at the end of a transmission? Labviww am the user for the computer and software.

A search within the install software folder for dll seems to indicate that they didn’t, by the way. I have to idea how to make it and be sure that they are retrieved at perfectly the same time?

What does it meant? Learn more about Choosing a Thermocouple Measurement Device.

I’m facing the same problem at the moment. You already told you can use VISA for communication, so just use it! Unfortunately this is likely a limitation of the device. Unfortunately Dennis can’t answer your questions, someone else might. Message 12 of Yes, I know there is a driver for this device.


Signal Recovery Dual Phase DSP Lock In Amplifi – Instrument Driver – National Instruments

Attached is my code. This llabview why user friendly manuals, interfaces and devices are so much more important than even 10 years ago. Message 5 of Labvifw system will have a formula but for the general form of a serial Rtotal and Xtotal fort his purposes a formula was derived experimentally and theoretically from a RC circuit with a 1.

The block diagram is the ugly wiring behind the device the front panel is the good looking easy to use user friendly push and switch panel.

The R and C were treated as unknowns and made up the system. The shield grounding methodology can vary depending on the application.

I don’t think anyone can help unless you provide some information.
