DF6JB’s Plotter 2010-03-08
|
|
Plotter
is a utility to graphically display and edit numerical data. Above of
that it compute self- and cross correlations of data series and
statistical measures like the Allan Deviation and more. Now includes an
All-Tau option for stability statistics

EZGPIB 2012-12-17
|
|
EZGPIB is a tool for easy GPIB, TCP or serial based data acquisition in conjunction with a Prologix
GPIB to USB interface. Now works for DLL based plugin cards & USB
controllers too. Even newer: Works with the latest Prologix LAN
GPIB interface. Here you find a EZGPIB ProfiLab Demo

AVR PPSDIV 2008-09-06
|
|
Tom Van Baak has done it for the PIC world of microcontrollers: A single chip frequency divider called PPSDIV
that will generate a low jitter set of output frequencies at 100 kHz,
10 kHz, 1 kHz, 100 Hz, 10 Hz, 1 Hz, 0.1 Hz and 0.01 Hz from a
single 10 MHz reference input. Now I have translated Tom’s original
code into the AVR world of microcontrollers and you can download a
complete AVR Studio project AVR-PPSDIV
that will enable an AVR Mega microcontroller to perform the same. Due
to the shorter cycle time the 100 kHz have an almost perfect 1:1 duty
cycle. Should run on any AVR that has an complete port A available
since that one is used for the output. The smaller AVR chips feature
only a complete port “D”. For that reason you find a version of
AVR-PPSDIV here that makes use of pord D.

01/May/2021:
my apologies for the awfully formatted paragraph. Unfortunally Ulrich
used a HTML authoring tool unknown to me and I am not able to just add
a similar table block without destroying the whole page formatting.
So, here are the new download links. Many thanks to Richard Radl for providing the package.
This is an
EZGPIB file provided by Roman Budek for a HP3478A connected via a
Keysight H2357B GPIB controller. Roman states that BenchVue does not
support the older instrument. The Keysight IO panel allows triggering
device but not datalogging it. EZGPIB is able to fetch data and to
control the instrument.
