The slowest plotting speed is always set in the factory. In the case of shipments by post, rail or carrier it is recommended that the original packing is carefully preserved.

If the DUAL button is depressed, both channels are work- ing. See full item description. They are also described in more detail below. With sinusoidal signals, observe the Subject to change without notice Mil zero crossover point transitions; the sine peaks are less accurate. The maximum sensitivity and input impedance are now the same in both deflection directions.
This short circuit should be repeated several times im- portant when changing tubes! For this purpose, select with the 2.

Slope; positive or negative. Memory switchover Using the built in second memory, which is switched on by depressing the 2. Questions and answers about this item. Examples of Test Displays: In the LF position low frequency frequencies above 1 kHz in the internal and external trigger signal are increasingly attenuated, high frequency disturbances and noise are therefore suppressed.
If your circuit has a high input impedance e. The single sweep mode is not applicable in analogue oscilloscope operation. M6 Subject to change without notice With all attenuator probes, the maximum AC input volt- age must be deratedwitb frequency usually above 20 kHz. Frequency and pulse duty factor are not critical here.

To protect the CRT, work with the minimum brightness required for by the measuring task and the surrounding illumination. However, external triggering should be used only if internal triggering is not possible e. The dot density is high max. Adjust signal to desired display height with attenuator switch. Most cathode-ray tubes develop X-rays. The calibra- tor output of the HM fulfills these conditions when the 1 MHz button is depressed.
The values stated above and the trig- ger thresholds internal 5 mm; external 0. M8 Subject to change without notice 1 kHz compensation This C-trimmer calibration connpensates the capacitive loading of the oscilloscope input approx.

The two signals must generally be synchronous, but they may certainly have a constant phase difference. Overdrive in the X direction can be detected easily by left or right sided flattening clipping.
D27 Adjusting Plan A 1 Subject to change without notice 6. Too high hum levels can frequently be the cause of faults which are otherwise unexplainable. Intermediate values can be set with the small concentric knob variable. Regulated DC power supplies: If the corresponding PLOT button is depressed again, a complete plotting pro- cess restarts.
The use of test cables with high imped- ance circuits is only recommended for relatively low fre- quencies up to approx.
Single sweep is recom- mended in particular for aperiodic signals or single events, such as a switching on process. The coupling mode and the resulting frequency range of the trigger signal can be switched over both internally and externally with the TRIG, trigger selector switch.
Two stored signal images can also be compared with one another using Channel II as well. This lamp indicates memory readiness for single sweep mode. DC cou- pling is also recommended for the display of logic and pulse signals, especially if the pulse duty factor changes con- stantly.
If it is a question of pulses hameeg the same shape, read off at steep edges. No additional import charges at delivery! Image not available Photos not available for this variation. The pushbuttons engage only auxiliary functions.
