1. DC voltage measurement (V=).
This function enables the user to measure DC
voltages (only for DC input coupling)
Meter readout
Fig 27
Useful tip for measuring DC voltages:
The readout can be set to zero (reference)
regardless of the trace Y-position by
keeping the AC/DC key pressed down.
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 voltage (Vpp).
The signal's peak-to-peak voltage (difference
between highest and lowest value) is
displayed.
5. dB ref = 0dB
Display the dB reference.
To set the current signal level as zero dB
reference, hold ‘AC-DC-GND’.
Remark : if the current level is too low or if it
goes off-screen, the reference will not be
accepted.
6. Peak power (W
↑
)
Peak power calculation into selected
impedance (2, 4, , 8, 16 or 32 ohm).
