I have the DTS-2077. Here's some random thoughts:
1. Recommended maximum input voltage is +-1V1. Damage level is 1V7.
2. Square waves are required for all inputs. A rise time of 1 ns. is
barely adequate and will likely degrade your results.
3. Timelab supports the DTS-2070 series so it's easy to measure ADEV,
frequency, etc. if you have GPIB capability.
4. One thing I think qualifies as a pearl is what Wavecrest calls the
'strobing voltmeter'. Anyone else would call it a digital oscilloscope
with an equivalent sampling speed of 100 GHz. I've attached a
proof-of-concept test of a pulse that I fed into the DTS. The
horizontal divisions are 100 ps/sample, vertical is volts. I could have
gone to 10 ps/sample, but didn't need to.
