Coupling
AC:
the input signal is capacitively coupled to the input amplifier/attenuator. Only the
AC components are measured.
GND:
the input signal is broken and the input amplifier/attenuator is connected to
earth. Use this position for selecting a reference point on the display.
DC:
the input signal is directly connected to the input amplifier/attenuator. Both AC
and DC voltage are measured.
X10:
When measuring high voltages set the measuring probe and the oscilloscope in
the X10 position.
volts/div:
The signal on the screen can be enlarged or reduced vertically by adjusting
the displayed voltage per division. (V/div = voltage per division).
Readout set-up
Press the button to call the menu. A table with all possible readout setups
appears. Select the desired readout.
Vdc:
This functon enables the user measure DC voltages
(only for DC input coupling)
.
Vmin:
The signal's negative peak voltage (difference between zero and lowest
value) is displayed.
Vmax:
The signal's positive peak voltage (difference between zero and highest
value) is displayed.
Vpp:
The signal's peak-to-peak voltage (difference between highest and lowest
value) is displayed.
Vrms:
The true RMS value of the AC wave is calculated and converted to
voltage.
Vtrms:
The true RMS value of the wave (AC+DC) is calculated and converted
to voltage.
dBm:
The measured signal (AC only) is converted to dBm (0dB= 0.775V).
dBgain:
The gain between channels 1 and 2.
Channel 1: input signal
Channel 2: output signal
Wrms2 - Wrms4 - Wrms8 - Wrms16 - Wrms32:
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. To choose the different loads, first highlight the power readout and
then press the right cursor key.
