The -2500 supply is nearly identical to the +3500 supply. We will
post some photos on the disassembly process. We also had to
disassemble the +3,500 supply because the 200 Meg resistor had gone up
in value. It showed only 1,900 V
Hi
That’s a very good price for what it is !!

I don't know how they're done in VMWare, but in VirtualBox, you have to setup
the USB configuration for the VM before you start it. You just click the
machine, settings, then USB, then add a device, then select from what's
available. Which means you have to have it plugged in and enumerated fi

Eventually you will want multiple inputs to any chip like this. The more I/o
the more crosstalk.
Properly done, differential inputs will reduce your crosstalk quite a bit. You
might as well debug that part of it now.

Hi, Attila!
Somewhere you'll have to produce sharp differential edges and this
semi-analogue stuff is probably hard on a chip shared with thousands of
other gates and a digital process. Going differentially into the chip will
reduce the effects of ground bounce etc a lot.
This is what you can ex
John,
Thanks for the reply.
I'm obviously missing something as I can't see the GPIB-USB-B or the
ethernet connected GPIB-ENET.
It's really as simple as going to aquire->HP5371/5372 and the interfaces
should be in the list, correct?
Thanks,
Bob

I believe you have to configure the Virtual Mach
Try running the 32-bit version (timelab.exe) instead of timelab64.exe, even if
the VM supports 64-bit execution. That can sometimes help with compatibility.

So I'm trying to run timelab in a windows 7 VM with a GPIB-USB-B interface.
Anyone ever tried such a thing?
The NI explorer sees the interface but nothing else does.
Pointers welcome!
Data on a bunch of oscillators as soon as I get it to work...:)
Thanks,

Differential inputs, either LVDS or PECL compatible, together with a fast
single supply comparator for the CMOS to PECL to LVDS/differential PECL would
be the conservative approach. Ultra fast comparators with aaa delay belo

M12+ or M12+T?
There are two different versions of firmware, same hardware.
The M12+ does NMEA and Moto bin, the +T does Moto Bin only.

TAPR has announced a new kit that may be of some interest here:
https://www.tapr.org/gps_exp-kit.html
It's certainly well worth the $30.
