NI PXIe-8370, PCIe-8371, PXI-GPIB upgrade

Saturday, November 26th, 2016

I was using NI PXIe-8105 embedded controller in my NI PXIe-1062Q chassis but the speed is too slow.  Recently I have acquired the controller card PXIe-8370 (about 800MB/s; pcie x 4).  The PCIe-8371 card can be put  in my computer PCIe x 16 slot (for VGA card) and function perfectly. Mother Board is Gigabyte H77N ITX version. OS is WIN7 64bit version and both the NI and audio precision system two cascade is working fine with an I5-3570K CPU.  The fan noise of the NI chassis is even lower then before and the power loading is lesser without the embedded controller!

.

Without the embedded controller, I lost some I/O like parallel port, GPIB etc… and thus I have to get one more PXI-GPIB card.  Later I find out my Agilent 82357B USB – GPIB controller is also working fine in with NI system.  In the past, I plug the USB into PXIe-8105 but cannot make it work properly!  Thus the PXI-GPIB card become excess!

Key sight DSO-X 3024T firmware update

Friday, November 25th, 2016

Keysight has released new firmware 04.08 for DSO-X 3024T and here are the photos of upgrade process.  The whole process take about 5-6 mins.

It has made lots of changes in this version and details refer to website link:

Audio Precision USB APIB Adapter (inside photos)

Saturday, November 19th, 2016

I am using PCMCIA to APIB to control my AP system two cascade under winxp.  The PC is celeron with PCMCIA slot and thus is running very slow.  One way is to use a PCI to PCMCIA adapter if PC is to be upgraded.  I just have one i5  – 3570K with 8GB ram and ITX Mother Board and thus no PCI slot!

Recently I saw a old AP USB to APIB adapter on ebay for about US$350 and thus I think it is time to upgrade the speed of the AP system. 

Here is some photos inside the adapter.

Tektronix TDS1012B internal photo and firmware update

Friday, October 14th, 2016

I acquire this old scope cheap and found the firmware is still 22.01.  I need to find a small USB drive using CF card of 1GB before I can update the firmware to 22.16.

I do not like the design of the power supply as some regulators are without heatsink and also two of the heatsink is too small.  After operating it for 15 minutes in 30 degC room temperature, I can smell the hot air come out from the top of the scope.  I bit worry on the temperature of the heatsink and also it is very close to the E-cap which will speed up the aging effect!

National Instruments PXIe-1062Q, PXIe-8105 & PXI-4130

Saturday, December 12th, 2015

These were newly acquired in Nov 2015 from eBay.

PXIe-1062Q: for both PXI and PXIe cards with power supply.

PXIe-8105: controller for the system with upgrade to IDE 120 GB SSD from Kingspec (China) and 4 GB (2 x 2GB) DDR2 RAM.  Actually I found all on hand DDR2 ram with higher speed with work on this controller.  BIOS has also been updated to the latest version 1.3.3.  Speed wise is ok fast now with SSD and 4GB ram under window 7 32bit.

PXI-4130: SMU with two output: +/-20V max 2A and 9V 1A.  This supply can be programmed to check transistors or FETs under Labview.

The total cost is about USD$1500 but if getting a SMU with dual output will be much more expensive!

I shall learn and try to develop a program to sort the mosfet 2SK1530 / 2SJ201 soon.  Sorting of the Toshiba 2SK170 / J74 is also very good as the speed is supper fast and reading is stable with no oscillation concern.

USB GPIB adaptor 82357B from Agilent has big issue to link up with other equipment on the NI controller even I follow the steps as what is advised by Aglient website.  Finally I get the original NI GPIB cable Type X13 183285-02 and every things works perfectly.  No wonder the price of second hand USB-GPIB cable from Agilent is half of that from NI!

Changing the 3V back up battery in the PXIe-8105 controller must need reset the reset jumper pins or else the controller cannot boot up at all.
