- >16 bit measurements of 1ms acquisition periods
What is it? How does it work?
In addition to the standard LEMO outputs, the V2F100 has 2-phase quadrature output and absolute digital SSI output available on the rear through a sub-D 15 connector. This enables a setting whereby both the magnitude of the voltage and the polarity is able to be output by the V2F100. SSI is usually used in motor and encoder controls, but is available on a number of instruments for beamlines.
The first chart above shows a comparison of the V2F 1MHz and the new V2F100. This test, performed at Diamond Light Source emphasises that even at the 50Mhz the test was run at, any experiment with an integration time below 0.3s suffers significantly from poor statistics from the 1MHz V2F – the 100MHz V2F100 moves this problem out by two orders of magnitude.
