Re: [time-nuts] Wavecrest DTS 2077 Service Manual?
There is one calibration that can only be started by a GPIB command. I ran into that, my unit constantly said something like "xxx calibration required" or similar during power on. No way to do it with the front panel buttons. It is easy to start that cal using Visi, or via sending a GPIB command if I remember correctly. Unfortunately I lost my Visi CD.. bye, Said In a message dated 11/19/2012 01:47:55 Pacific Standard Time, h...@deriesp.demon.nl writes: Hi, The Wavecrest DTS 207X has a number of proms and also battery back-up devices.

Re: [time-nuts] Wavecrest DTS 2077 Service Manual?
Adrian, Take a look at Patent # US 6226231 B1 for a schematic of the interpolator used in the Wavecrest DTS-2075. It may be similar to what you are trying to troubleshoot and might give you some ideas. Richard > In the meantime I heard that Wavecrest is not distributing service > manuals.

Re: [time-nuts] Wavecrest DTS 2077 Service Manual?
Hi Henk,
as by the component date codes, my unit is probably from 1998. Some -
possibly replacement - boards have date codes up to late 2000.
Upon power up this error message is displayed:
'Path Checksum Error - Perform External Calibration'
DC Cal. finishes, but the next step with cal outputs connected to inputs
fails immediately.
The measurement display says: MEAS: no pulses found
When I try internal cal., I'm getting 'Cal init failed - No IQM Intr'
displayed.
Apparently the DC calibration happens on the large input board, while
the other cal steps are addressing the IQM ('Test Interval Quantizer
Board').
It seems like the failure is IQM board related. When I run calibration
with the IQM board pulled, my unit still behaves the same way.

Or are you sure that it is hardware? How old is your DTS?
Henk
In the meantime I heard that Wavecrest is not distributing service
manuals. All repair is depot.repair.
This makes me considering if I should take the chance on a second unit,
hoping to get one working out of two, or simply to give up and accept
that these boxes are only intended to be used as door stops of land fill
once defective... I've never been confronted with such a poor customer
sevice attitude before.
Nevertheless... is there anyone who has acquired some experience with
the DTS-series innards who would be willing to share his knowledge?

Anyone have a Wavecrest DTS 2075/77/79 service manual?
I've recently got a DTS 2077 that however turned out to be defective.
There was a power supply failure that I could fix, but there is still
a power-up selftest error message and calibratin fails.
