GXAO1642 Error Code "-23" - Created on Tuesday, February 9, 2021

2/9/2021 3:11:56 PM

By Greg S. on 2/9/2021 3:11:56 PM
Hi, I'm using a GXAO1642 and when I run the self test command GxAOSelfTest(), it returns an error code of "-23". There's no information in the user manual about error codes. The GxAOSelfTest() is supposed to also return an array of results and a "string that summarizes the results of the self-test" according to the user manual, but both the array and the string are empty after running this test. The only result is "-23".
Thanks,
Greg Smith

By Dale J. on 2/9/2021 4:33:31 PM
Hi Greg,
Error codes are listed in the GxAoGetErrorString() function. Error -23 is "Illegal board handle". An empty array and self test string would be expected if you are not communicating with the DLL, but I think the real problem is that the GxAOSelfTest() function only applies to the GX1649 and GX1632 instruments. The documentation is a bit vague on this, but if you read through the full function text for the self test, you'll only see the GX1649 and GX1632 referenced there. Also, if you run the GxAo panel, and initialize a GX1642, the Self Test button is grayed out.

Regards,
Dale

You need to call GxAoInitialize() or GxAoInitializeVisa() prior calling GxAoSelfTest, Use the handle that you got from initialize and pass in to the selftest function.

Ethernet interface with GX3700e - Created on Wednesday, March 18, 2020

3/18/2020 9:14:20 PM

By Sean P. on 3/18/2020 9:14:20 PM
I am new to understanding this card. I am looking for a way to interface with his board via Ethernet. What would be the best way to send data to the GX3700e through this protocol?

I was thinking of using a 68 pin VHDCI to RJ45 adapter cable but perhaps there is an expansion board out there that can do this.

Thank you in advance.

Control GX7010C PXI trigger lines - Created on Monday, January 13, 2020

1/13/2020 1:55:02 AM

By Lennart H. on 1/13/2020 1:55:02 AM
Dear Support Team,

we are using a GX7010C chassis to control 8 cp246 cards (kinetic systems). To start/stop data acquisition on all cards simultaneously they need an external trigger signal on PXI trigger lines:
"To start an acquisition, use the PXI Controller to apply a pulse on PXI Trigger Line 1. This should start all the CP246 acquiring data.
To stop an acquisition, use the PXI Controller to apply a pulse on PXI Trigger Line 2. This should halt the acquisition process."

How can I use the GX7010C chassis to generate a software controlled pulse on PXI trigger line 1 by using LabView? I didn't found such a function in the GXChassis.llb LabView libary.
(C:\Program Files (x86)\Marvin Test Solutions\GxChassis\GXChassis.llb)

How can I configure the chassis, so that it generates a time delayed pulse on PXI trigger line 2? The delay between pulse 1 and 2 should be set by LabView.

Hi!

I'm new to using this hardware and I would like to know how do I connect an SMU channel as a source/power supply and be able to monitor its voltage output and current?

I'm not sure what the +FORCE is for. I found another product online that has the output taken across the HI and LO (this allows you to monitor the current) and the sense lines allow you to monitor the voltage. Can you guys help me out with this?

For channel 0, I have:

Pin 1 --> VIA-OUT --> Channel 0 Out (+FORCE)
Pin 2 --> HI Guard A --> Channel 0 HI Guard
Pin 3 --> GND_S_A --> Channel 0 Remote GND Sense (-)
Pin 14 --> KLVNA_IN --> Channel 0 Remote Sense (+)

Thank you,
Manny

GX7944 endpoint mode ? - Created on Monday, November 10, 2014

11/10/2014 7:06:26 AM

By Alexander K. on 11/10/2014 7:06:26 AM
Good day.

Can you help me ?
Can GX7944 work in endpoint mode ?

We want tou use (try to find a solutions) this card like a additional processor for some calculations with a data from Ethernet interfaces.
This card must be work on bus like a I/O module (after additional programming).
We plan to insert it in a peripherial slot in chassis.
If I think well - we have to problem:
1. This card is a controller for PXIe bus and (may be) can't work like a peripherial module (controller is another card).
2. This card inserting in a peripherial slot and can't be power supply like a controller (see PXI specifications for power for module's type).
3. Can it work in NI chassis or only in Marvin GX 7600 PXI Express chassis ?

Wait a answer.
Thank you.

Hi,
I am currently running a number of Geostest systems here at work all of which are using the Geotest GTXI PCT Board 250220 Rev D. board for bus expansion. I'm looking to pick up some spares for these cards in the event of failures. I was curious if anyone knew if the GTXI PCT Board 250220 Rev. C would fully function in place of a Rev. D or what kind of issues I may run into upon replacement. Any explanation as to the difference between these two board revisions would be a great help. Thanks.

DIO Boards firmware - Created on Monday, March 12, 2012

By Stephane L. on 3/12/2012 4:59:17 AM
Hi,
There are updates for DIO sofware drivers in the download part of the website, but I suppose some of these updates also need firmware updates.
We're using GX5295 with 4.1.54 drivers and 0xB311 firmware (as seen in about panel of GTDIO panel.exe).
Are there any updates (I saw that 4.1.52 requires 0xB930), and where can I get them?
Thanks for any help

Stephane

By on 3/12/2012 10:49:15 AM
Hi Stephane,

The latest Gx5295 firmware is the attached “2355-000-02__revB_100MHz_b930.jam” file.

DIO firmware upgrade:

1. Download the “2355-000-02__revB_100MHz_b930.jam” file to your system.
2. Open the DIO virtual panel and initialize the Gx5295 board.
3. Click on the About tab and then on the “Upgrade Firmware” button.
4. A file open dialog will open, locate the “2355-000-02__revB_100MHz_b930.jam” and click Open.
5. The firmware upgrade will start, and the progress bar will notify you when it’s done.
6. When done you will need to shut down and reboot your system.

Thanks,
Tamir

Adding External Source- GX1838 DC Power Source - Created on Monday, December 13, 2010 (Solution Avaliable)

By Avital A. on 12/13/2010 11:12:02 AM
Hello,

I'm using GX1838 card. I use four outputs, nd each of them should output 0-6v and 0.5A minimum. I made checks, and realized that I have to use the external rail source (instead of the internal). My question is: how should I use the external source? do I have to connect to it a programmable power supply? How am I supposed to implement using the external power source in hardware and software?

Regards,
Avital.

Trouble getting fast frequency measurements from GTX2200 - Created on Monday, April 26, 2010

4/26/2010 12:40:11 PM

By Nathaniel G. on 4/26/2010 12:40:11 PM
I have a GTX2200 in an NI PXI-1044 chassis.

I have followed the user guide and set the gate time to 500/250us and trigger level accordingly (Fixed, .5V), but the max output I get is 100 Samples/second. I have affixed a standard frequency reference, 10 MHz to Channel A.

Is there a test GUI I can use to see how fast it is acquiring samples?
Are there other tips, besides those in the user's guide, that I should follow?

By Dale J. on 4/26/2010 3:15:30 PM
Nathaniel, what function are you using to measure the frequency? The suggestions in the user guide are for measuring to an array - GxCntReadMeasurementArray(). Also mentioned in the manual: The maximum number of measurements depends on the CPU speed, system configuration and number application running at the background. See the GxCntReadMeasurementArray function on how to achieve high number of measurements.

Regards,
Dale

By Nathaniel G. on 4/27/2010 2:13:27 PM
Thanks Dale.

This is precisely the function I am using, and from which I pulled those gate/level settings.
The embedded controller is a 2.2 GHz P4, so I do not think CPU speed is the issue. Can you at least confirm that you or others get higher frequency performance?

By Dale J. on 4/27/2010 4:01:36 PM
Nathaniel,
I'll put a test bench together and let you know what I find. Would it be possible for you to send me your code for review?

Regards,
Dale

$$-PS: I confirmed the slow measurement speed and reported to engineering for review-$$

By Tony L. on 8/13/2009 6:05:20 AM
There should definately be an adjustment pot for the 10MHz output. This is a very poor design. We have so many problems with this and if it is out we have to send it back to Geotest! So far we have about a 40% failure rate with the 10MHz clock out.

Explanation for the difference about "resolution" and "accuracy" of GTX22x0 - Created on Monday, March 30, 2009

Dear Sir,
Could you please do me a favor to make an explanation for the difference about "resolution" and "accuracy" of GTX22x0?

Leo Shan
Beijing Queentest Technology Co., Ltd.

By on 4/1/2009 12:12:33 PM
Leo,

The resolution of the instrument can be defined in two ways.

1) The number of digits that can be determined for any given measurement (a function of gate time).

2) The granularity of the measurement in terms of Hertz or Seconds (depending on measurement type).

The accuracy of the measurement is referring to the possible maximum error (+ and -) relative to any given measurement, which is basically determined by taking the resolution in terms of Hertz or Seconds (depending on measurement type) and adding/subtracting the time base error which is a function of the clock oscillator.
