I'm trying to save a waveform in PS6 for use as a test reference (output) signal. I need to test some control systems that use 0-to-5 v analog input centered at 2.5 volts. The goal is to feed the control system a reference signal of known definition (frequency, amplitude) to measure/monitor the response of that system. Straightforward stuff w/ no high frequency or high voltage or any tricks. A sine wave at various frequencies from fractional Hz to a few Hz w/ 2.5 volt offset shouldn't be too much to ask, should it?
It is proving problematic for several reasons:
PS6 Crash during CSV file format save
Will write .MAT format but won't read it
Waveform generator won't generate a wave form w/ more than a 1 volt offset.
Using math channels to generate some combination of terms to get the 2.5 v offset doesn't allow for either the frequency sweep or simply saving in some readable format.
The only (single!?!) reference to these issues are in the forum from 2009, which really does NOT give me a warm a fuzzy. Have these issues existed so long and never been addressed, or is there a workaround using the PicoLog suite? This simple test task of generating a low voltage low frequency waveform in some sort of stored format for playback as an external reference on demand should be trivial at this level of lab test/measurement tool. I hope it doesn' t take a huge patchwork of partial fixes or bandaids to achieve this type of solution, but initial efforts indicate that may be the case if its even possible at all!
Thank you for the help-
