Subject to change without notice
1 Hz – 1 MHz
These AC square wave signals can be used for probe
adjustment and judgement of the frequency response. As
the frequency and the pulse duty factor accuracy are not
important for such purposes, these values are not specified
and are therefore relatively inaccurate.
Dependent on TB
The square wave signal’s pulse duty factor differs widely in
most settings from 1:1. In time deflection ranges from
500 ms/div to 1µs/div. the period length and the time deflection
coefficient are equal; this allows you to check the time base
accuracy. The smallest period length is 1 µs (1 MHz) and
consequently time coefficients <1µs/div do not change it.

Concentric socket
This socket serves as the output for the signals described
under item CAL. SEL.
[35] . The output impedance is approx.
MAIN MENU
The instrument software contains several menus. The following
menus, submenus and menu items are available:
1. ADJUSTMENT contains the submenus:
1.1 AUTO ADJUSTMENT with the menu items
1.1.1 SWEEP START POSITION
1.1.2 Y AMP
1.1.3 TRIGGER AMP
1.1.4 X MAG POS
1.1.5 CT X POS
Calling one of these menu items requires that no signal is applied
on any input. For further information note „Adjustments“.
1.2 MANUAL ADJUSTMENT contains menu items that are
only accessible for HAMEG workshops.
2. SETUP & INFO contains the submenus:
Main Menue
50 Ohm. For high impedance loads (Oscilloscope approx.
1 M Ohm, Digital Voltmeter approx. 10 MOhm) the output
voltage is either 0.2 Volt DC or 0.2 V
pp
(AC, square wave).
Under “First Time Operation” section “Probe compensation
and use” the most important applications of this signal can
be found.
[37] CT – Pushbutton and 4mm banana jack
Briefly pressing the pushbutton switches the instrument
over from oscilloscope to “Component Tester” mode and
vice versa.
This mode is indicated by the READOUT which displays
”Component Tester”.
One test lead is connected to the CT socket. The second test
lead uses the ground socket
[27] .
Please note ”Component
Tester”.
The maximum test voltage is approx. 20 V
pp
under open
circuit conditions, while the max. test current under short
circuit condition is approx. 20 mA
pp
.
Briefly pressing the CT-pushbutton switches back to the
previous oscilloscope operating conditions.
2.1 MISCELLANEOUS
Active functions are indicated by „x“. SET switches over
from active to inactive and vice versa.
2.1.1 CONTROL BEEP. Acoustic signal confirms error free
operation.
2.1.2 ERROR BEEP. Sounds in case of operating error.
2.1.3 QUICK START. Reduces the waiting time after POWER
ON, as neither the HAMEG logo nor the check and
initialisation are displayed.
2.2 FACTORY
Submenus are available only for HAMEG authorized service
workshops
2.3 INFO
Displays information regarding the instrument’s hardware
and software.
