5.2 Probe compensation
The first time you connect the probe to an input channel, you must match the probe to the input
channel. A probe that is not or incorrectly compensated results in measurement errors. Perform
the probe compensation as follows:
1. Set the attenuation factor of the probe to 10X in the menu, set the switch on the probe to 10X
and connect the probe to channel 1. When using the hook tip, make sure it stays securely
attached to the probe. Connect the probe tip to the signal connector of the probe compensator
and connect the terminal of the reference cable to the ground terminal of the probe
compensator; then press the AUTOSET button.
2. Check the displayed waveforms and adjust the probe until correct compensation is achieved

Abbildung 3.1 Tastkopfkompensation
3. Repeat the procedure if necessary in order to obtain an image that is as even as possible.
5.3 Setting the probe attenuation factor
The probe has several probe attenuation factors that affect the oscilloscope's vertical scale factor.
If the setted probe attenuation factor should be changed or checked, press the key for the function
menu of the respective channel and then the selection key corresponding to the probe until the
correct value is displayed.
- 15 -
This setting remains in effect until it is changed again.
Warning:
To avoid electric shock, you should always keep your fingers behind
the safety ring on the probe.
To protect you from electric shock, do not touch any conductive metal
part of the probe tip when it is connected to a power source.
Before any measurements are carried out, always first connect the
probe to the oscilloscope and then the earth terminal to the housing of
the device under test.
Note: The attenuation factor of the probe is in the menu presetted to 10x.
Make sure that the value set on the probe's attenuation switch corresponds to the
attenuation value set on the oscilloscope.
The values that can be set with the switch on the probe are 1X and 10X (see picture).
Note: When the attenuation switch is set to 1X, the probe limits the bandwidth of the
oscilloscope to 5 MHz. You need to set the switch to 10X if you want to take
advantage of the full bandwidth of the oscilloscope.
Safety instrucstion for using the probe head
The protective ring around the probe head handle prevents unintentional reaching over or slipping
and thus contact with any metal parts that may be live (see error! Reference source could not be
found).

Pressing the CH1 ～ CH2, CH1 ～ CH4 buttons has the following effect:
• If the waveform is switched off, it is switched on and the channel menu is displayed.
• If the waveform is already switched on, the channel menu is also displayed.
• If the waveform is already switched on and the channel menu is displayed, switch the waveform
and the channel menu off again with this action

6.1.1 Setting the channnel coupling
As an example, let's take a square wave signal on channel 1 that contains a DC bias. Proceed as
follows:
1. Press the CH 1 button to access the CH 1 menu
2. Press pairing in the channel menu
3. Select DC to view the DC and AC components of the signal
4. Select AC to display the AC components of the signal
6.1.2 Setting the probe attenuation
For correct measurement results, the settings of the attenuation factor in the operating menu of
the channel should always correspond to those of the probe (probe compensation page 15). If the
attenuation factor of the probe is 1: 1, the setting for the input channel should also be X1.
Proceed as follows, e.g. to set a attenuation factor of 10: 1 for channel 1:
1. Press the CH 1 button to enter the menu
2. Select the Sensor function. After that select the attenuation factor 10x on the left side of the
display
6.1.3 Current measurement
In order to perform a current measurement with the oscilloscope, you have to perform the voltage
drop on a resistor / shunt. In the following example, the current is measured by the voltage drop
across a resistor that has 1 Ω:
1. Press the CH 1 button to enter the menu
2. Now select the Probe function and switch from No to Yes in the Measurement Current
selection on the right. Now the setting for the V / A display appears. This shows the
respective display ratio of current to voltage. You can change this ratio by pressing the
button using the arrow keys and the + and - keys
6.1.4 Invert a waveform
The inverted waveform rotates the displayed signal 180 degrees from the phase of the ground
potential.
1. To invert the waveform, press the CH1 key
2. Press the Invert button to toggle between the On and Off settings

6.1.5 Setting the bandwidth limit
When the high frequency components of a waveform are not important for your analysis,
bandwidth limiting can be used to suppress frequencies above 20 MHz.
Proceed as follows:
1. Press the CH 1 button to enter the menu
2. Select the limit value function
3. Now select the 20M function to only display frequencies up to 20 MHz
4. Select the Full Band function to measure all frequencies up to the maximum bandwidth
6.2 Set the horizontal system
To set the horizontal system, the HOR function key and the two rotary knobs are used as follows:
- Press the HOR key to activate the horizontal setting
- With the upper rotary knob you are now able to determine the horizontal position of the
respective channels
- The sampling rate of the respective channel is set with the lower rotary knob
- Press the HOR key again to activate the waveform zoom function
6.3 Waveform zoom function
Press the horizontal HOR button twice and enter the horizontal zoom mode for the waveform. The
upper part of the display shows the main window and the lower part the horizontal zoomed
window. The horizontal zoom window is the horizontal enlarged part of the selected area in the
main window.

6.4 Operation of the function menu
The operating area of the function menu comprises 13 function menu keys: Trig Menu, Acquire,
Utility, Autoscale, Save, Measure, Cursor, Math, Decode, HOR, FFT, XY, P / F, DMM as well
as 5 immediate selection keys: Autoset, Run / Stop, Single, Copy, default.
6.5 Set the trigger system
The trigger determines when the oscilloscope begins acquiring data and displaying the waveform.
Once properly set, the trigger can convert a fluctuating reading into a meaningful waveform.
When the oscilloscope begins acquiring data, it records enough data to plot the waveform to the
left of the trigger point. The oscilloscope continues to acquire data while it waits for a trigger
condition. When a trigger is detected, the device continues to record enough data to display the
waveform to the right of the trigger point.
The trigger control area consists of 1 rotary knob and 2 menu buttons.
6.5.1 Single trigger
Trigger control
The device provides four types of triggers: single trigger (single), alt trigger, logic trigger and bus
trigger. Each trigger type has different submenus.
There are two ways to get into the trigger mode:
Button operation: Press Menu in the trigger field to open the trigger menu. With H1 you can then
select the extended trigger menu, which you can scroll (turn) and select (press) with the
multipurpose rotary knob.
Touchscreen operation: Press the house symbol to open the touch menu. Select Trig Menu
and then the trigger (Single, Alt, Logic, Bus) in the lower menu. The trigger type can then be
selected under Type in the right image menu.
Single: Uses a single trigger to display a stable waveform on both channels.
Logic trigger: Triggers a signal according tot he conditions of the logic ratio
Bus trigger: Sets bus timing triggers
Trigger description
The single, logic and bus trigger menus are described below:
Edge trigger: Occurs when the trigger input runs through a specific voltage level with the
specified slope.
Video trigger: Trigger on fields or lines for a standard video signal
Slope trigger: The oscilloscope begins to trigger according to the rate of rise or fall of the signal
Pulse trigger: Finds impulses with certain widths
Runt trigger: Trigger pulses that run through one trigger level but not the other trigger level.
