This also applies – within certain limits – to whole number multiples or fractions of the line frequency. Trigger signal inputto TRIG.

The display can be held and permanently stored with the HOLD I button – if the point of interest has travelled up to the hamge center, for instance.
All four buttons out for mono mode. In combination with “roll mode” is possible. It can be regarded as a multiple mod- ulated oscillation.
Applied signals have no effect in this case. It is possible to work with automatic triggering here. The above arrangement 2.

The triggering range covered with the LEVEL control is highly dependent on the amplitude of the signal displayed. This button is located in the section beneath the screen, adjacent to the focus knob. PLOT I is depressed first for this purpose. The limit frequencies depend upon the signal height adjusted with internal triggering. Handling of the CRT needs utmost caution. The vertical position of the dis- play depends upon the Y-POS.
Measurements Apply test signal to the vertical input connectors of CH. How- ever, they are read out from the two single memories after one another alternately and displayed on the screen. Using the 2 V CAL.

It is important that the sequence of firstly 1 kHz and then 1 MHz compensation must be followed but need not be repeated, also calibrator frequencies of 1 kHz and 1 MHz cannot be used for time calibration. Add to watch list. Horizontal Deflection X Bandwidth: The signal to be displayed can hhm connected directly to the Y-input of the oscilloscope with a shielded test cable such as HZ 32 and HZ 34 or attenuated through a xIO or xlOO attenuator probe.
As a result of intermediate storage, the reduction of trace brightness, normally observed at higher fre- quencies, is avoided. In principle it is possible to measure in any display position and at any signal amplitude. Practically every early failure is detected in intermittent operation by this. In this case, the connecting cable is matched directly to the high impedance input of the oscilloscope.

Larger deviations are corrected with the aid of a small screw driver with a blade hamsg of approx. As already described, simple signals can be triggered automatically in the AT position even though the repetition frequency may fluctuate. It cannot be strictly defined and must be assessed according to application.
This is detected if the trace position changes noticably when the small knob with red arrow cap at the CH.
When a horizon- tal line is overdriven, a bright dot is seen at the end of the line. Thus signal frequencies down to 0. If the time switch fine control knob is pulled out, the HM switches over to X-Y memory mode.
The openings for this haeg located at the bottom of the casing approx. Probe calibration and use The attenuator probe must be matched exactly to the input impedance of the vertical amplifier to ensure an undistorted display of waveforms. The repeti- tion frequency of the signal must therefore be significantly smaller than the upper limit frequency of the vertical amplifier. Before use, calibrate attenuator probe previously with built-in square wave generator CAL. Triggering includes hsmeg following: Horizontal resolution in timebase mode Hhameg I alone: The correct triggering setting type, coupling, edge direction, level is especially important in the case of single sweep, since without triggering the last stored signal remains unchanged in the memory and therefore is also displayed unchanged.
The “case history” of the signal before and ahmeg the trig- ger point is now visible. Pressing the CHOP, button has no effect. When the appropriate plot button is depressed, the plotter feed is switched on, the stylus lowered with a short delay and memory contents plotted out.
