•
Press F1 to select GROUND.
Both AC and DC quantities of the signal being measured are now intercepted.
•
The waveform is not displayed in this mode but the signal remains connected to the
channel circuit.
Channel bandwidth setup
•
If for example a signal is applied to CH1 which is a pulse signal that contains high
frequency oscillation.
•
Press CH1 to select Channel1.
•
Press F2 to set the BANDWIDTH LIMIT OFF so it is set up as full bandwidth.
•
The signal being measured can now pass through even if it contains high frequency
quantities.
•
Press F2 to set BANDWIDTH LIMIT ON so that frequency quantities higher than
20MHz in the signal being measured will be limited.
Vertical Volts/Div adjustment setup
•
The VOLTS/DIV range of the vertical deflection factor can be adjusted either in
coarse or fine tune mode.
•
In COARSE TUNE the VOLTS/DIV range is 1mV/div~2V/div. Tuning is in steps of
1-2-5. For example: 10mV - >20mV - >50mV - >100mV.
•
In FINE TUNE mode it adjusts in 1% of the current amplitude value steps.
For example: 10.00mV—>10.10mV—>10.20mV—>10.30mV.
Probe rate setup
•
To match the probe attenuation factor setup, it is necessary to set up the probe
attenuation factor in the channel operation menu accordingly.
•
For example when the probe attenuation factor is 10:1, set the probe attenuation
factor at 10X in the menu. This principle applies to other values to ensure the
voltage reading is correct.
•
The coefficients can be set to 0.001X, 0.01X, 0.1X, 1X, 10X, 100X, and 1000X.
Waveform inversion (Reverse Phase)
•
The displayed signal is inverted 180 degrees with respect to the ground level.
•
The vertical identification will display a reverse phase logo ↓.
