Direct voltages are suppressed but load the oscil- loscope input coupling capacitor concerned! The X signal is supplied through the input of Channel II. A, B and three positions for optinnum screen viewing Fig. On the other hand, a video signal hamge line frequency can be displayed with AC possibly also DC trigger coupling.

It should have the same uameg as stated above for the 1 kHz compensation. Decreases Y sensitivity by a factor of 2. Warning When opening or closing the casing, when repairing or when exchanging parts, the instrument must be iso- lated from all voltage sources. Button depressed -display and internal triggering from Channel II. Report item – opens hamdg a new window or tab. It is generally located in the probe itself. The signal edges are invis- ible during this adjustment.

Naturally the sequ- ence can also be reversed. This setting is then optimal. Capacitors in the instrument can still be charged even if the hhm has been isolated from all voltage sources. For the first time, probes in this price range allow adjustments of their HF-characteristics to match individually the input imped- ance of each scope.

It refers to the screen deflection with the X-MAG. The calibra- tor output of the HM fulfills these conditions when the 1 MHz button is depressed.

An item that has been worn previously.

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. Subject to change without notice M17 – The 2. The ground leads on attenuator probes are also particularly critical.

Otherwise there is a possibility in the AT position automatic triggering that the triggering point may change or that triggering may not occur at all with signals without zero transition.

If there is transport damage, the supplier must be informed immediately. Please enter a number less than or equal to 0. In combination with “roll mode” is possible. The protec- tive action must not be negated by the use of an extension cord without a protective hn. X-Y mode As already described, the unit is switched over to X-Y mode – as in real time operation – by pulling out the time base fine control knob. As a result of intermediate storage, the reduction of trace brightness, normally observed hameb higher fre- quencies, is avoided.

The following can therefore be displayed: They are used according to requirements. New storage is only possible on each channel when the relevant button is released out.

M Subject to change without notice X section: Generally when displaying different signals, both sig- nal voltages should only be picked up with hmm probes of absolutely the same impedance and attenuation. Casing, chassis and all measuring connectors are connected with the safety earth conductor Safety Class Hamg.

Vertical amplifier mode Channel I: A bright dot simultaneously traces the plot on the screen of the HM All that is required for operation of the time base is then just the time setting.

It hamrg possible to work with automatic triggering here. A particulartimebase setting suits each input signal frequency. However, the vertical display height on the screen is then limited to approx.

Feb 26, The two signals must generally be synchronous, but they may certainly have a constant phase difference. This is the case with bursts, for instance.

Dot density and internal trigger- ing are as already described for the sum. Both base lines are set onto the hori- zontal graticule center line with the Y-POS. This is interfaced via a 5 pole DIN rear panel socket. Please enter a valid postal code.

However if your circuit has a low input impedance e. With the time axis expanded fold X-MAG. In all cases where the oscilloscope band width must be fully utilized e. This amount is subject to change until you make payment. However, there are still hameeg display modes in the mem- ory mode: If measurement, fault finding or calibration on the opened instrument is unavoidable, this should only be performed by an expert who is familiar with the risk involved.

Standard attenuator probes on the oscilloscope normally reduce its bandwidth and increase the rise time. If the trace is suddenly no longer visible after applying the signal voltage, it can be that the signal amplitude is much too large and totally overloads the vertical amplifier.

If it is set to LF, noise and interference frequencies which could possibly cause premature triggering are sup- pressed above 1 kHz low pass filterbut the low frequency signal components um including DC – are transmitted.
