DS-2000 Frequently Asked Questions

Question number FAQ-0717

What voltage is output from the monitor on the back of the DS-2000 series main unit? Also, is there any filtering applied?

When the voltage level is the same as the full scale of the voltage range, the output voltage will be 1.414V (1 Vrms). Additionally, the A-weight, B-weight, and C-weight analog filters set through input → voltage range settings → filter selection will be applied.

for example

Voltage range: A Vrms (RMS value)
Input signal: B V (peak amplitude)
Monitor output voltage: C V (peak amplitude)

In that case, it can be determined as follows by proportional calculation.

(Example)
A = 3.16 Vrms range, B = 1 V (peak amplitude) when;

C = 1 ÷ 3.16 = 0.316 V (peak amplitude)

will become.

Note
The voltage range setting allows for the selection of display options for Vrms (RMS value), dBVrms (logarithmic), and V (peak amplitude). The above formula is the calculation formula when using Vrms (RMS value). Please convert to Vrms (RMS value) when using dBVrms (logarithmic) or V (peak amplitude).
