The mezzanine MN6I is designed to measure instantaneous voltage values through six channels isolated from each other with differential inputs.

The mezzanine takes measurements in the following modes

  • “Once” - a single measurement is performed;;
  • “Block” - measurements are performed until a predetermined number of samples (results) is received on all channels;;
  • “Continuous” - measurements are performed on all channels in a continuous cycle until a stop command is received.
Mezzanine provides verification of the main technical characteristics in the self-control mode

Number of measuring channels
6
Measurement ranges of instantaneous voltage values and bandwidth
  • -150 to 150 V
  • -75 to 75 V
  • -30 to 30 V
  • -15 to 15 V
Measuring channel bandwidth by level minus 3 dB
0 to (7 ± 1) kHz
Limits of permissible basic relative measurement error of instantaneous voltage values during the period of obtaining measurement results (sampling period) equal to 50 μs and at ambient temperature (20 ± 2) ºС
  • ±[0,03 + 0,03·(Uм/Ux- 1)]% for the range from -150 to 150 V;
  • ±[0,05 + 0,05·(Uм/Ux- 1)]% for the range from -75 to 75 V;
  • ±[0,10 + 0,10·(Uм/Ux- 1)]% for the range from -30 to 30 V;
  • ±[0,20 + 0,20·(Uм/Ux- 1)]% for the range from -15 to 15 V.
where  Uм– is the value of the upper limit of the range, Uх – the measured value
Limits of permissible additional relative measurement error of instantaneous voltage values with a minimum sampling period for all measurement ranges,%
± 0.002 · T, where T is the deviation of the ambient temperature from 18 ºС (for the temperature range from 5 to 18 ºС) or from 22 ºС (for the temperature range from 22 to 40 ºС)
Additional relative error in the temperature range (20 ± 2) ºС
0
In the temperature range from 5 to 18 ºС and from 22 to 40 ºС the permissible relative measurement error is equal to the sum of the main relative error and the additional relative error
The sampling period is set the same for all channels in the ranges
  • from 5 μs to 82 ms in increments of no more than 5 μs;
  • from 82 ms to 1 in increments of not more than 100 μs.
