VPS10 Panel Scope
1. DC voltage measurement (V=).
This function enables the user to measure DC voltages (only
for DC input coupling)
Useful tip for measuring DC voltages:
The readout can be set at zero (reference) for any position
(see 'choice of input coupling', page 15) . Always use the
"run" trigger mode for DC voltage measurement
2. Maximum voltage (Vmax.).
The signal's positive peak voltage (difference between zero and
highest value) is displayed.
3. Minimum voltage (Vmin.).
The signal's negative peak voltage (difference between zero
and lowest value) is displayed.
4. Peak to peak (Vpp).
The signal's peak-to-peak voltage (difference between highest
and lowest value) is displayed.
5. True RMS readout (Vrms ac)
The area of the AC wave is calculated and converted to
voltage.
6. dBV measurement (dBV ac).
The measured signal (ac only) is converted to dBV (0dBV= 1V).
7. dBm measurement (dBm ac).
The measured signal (ac only) is converted to dBm
(0dBm= 0,775V).

8. dB measurement (dB ac).
The measured signal (ac only) is converted to dB (0dB= dBref*)
9. True RMS readout (Vrms ac+dc)
The area of the wave (+dc) is calculated and converted to
voltage.
10. dBV measurement (dBV ac+dc).
The measured signal (ac+dc) is converted to dBv (0dBV= 1V).
11. dBm measurement (dBm ac+dc).
The measured signal (ac + dc) is converted to dBm (0dBm=
0.775V).
12. dB measurement (dB ac+dc).
The measured signal (ac+dc) is converted to dB (0dB=dBref*)
*dB ref
The dB reference can be modified by selecting 'dBref' in the
settings table and closing the table by pressing the 'Mode'
button. The current value will then serve as 0 dB reference.
Audio power calculation.
The measured voltage is converted into power, supposing that the
voltage is measured across an impedance. The calculated power
can be displayed for loads of 2, 4, 8, 16 or 32 Ohm. The 2, 4, 8,
16 or 32 Ohm Charge for power readout can be modified by
keeping the 'Up' or 'Down' button pressed for a longer
time.
