MN6I
Item article:
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.
|
Number of measuring channels 6 |
Measurement ranges of instantaneous voltage values and bandwidth
|
|
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
|
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
|
The mezzanine can hardware-averaged voltage measurements. The number of averages from 1 to 16383 in increments of 1 |
|
