Select a valid country. Flow- ever, it is possible that a component fails only after a lengthy operating period. The signal is visible on the screen in this setting in the refresh mode.
To obtain a well-triggered display in this case, the assistance of the variable time control may be required. Have one to sell? Standard attenuator probes on the oscilloscope normally reduce its bandwidth and increase the rise time.
Ask a question – opens in a new window or tab. A particulartimebase setting suits each input signal frequency.
Multiple flashing also applies with single sweep except the timebase stops after the single advance. We do not advise measuring the post acceleration voltage of Amplitude measurement with Y fine control at right stop CAL. Subject to change without notice M7 Switching on and setting up Before switching on for the first time, the voltage set on the mains voltage selector of the HM must be com- pared with the local mains voltage adjustment see page M2!
The following can therefore be displayed: Two sockets provide for quick testing of the 3 junction areas in any small power transistor. How- ever, they are read out from the bameg single memories after one another alternately and displayed on the screen. II knob, so that in fact only the signal of Channel I remains visible.
Naturally the sequ- ence can also be reversed. The dot density is high max.
The instrument operates according to Safety Class I three-conductor power cord with protective earthing conductor and a plug with earthing contact. Single channel mode CH. Thus single events such as switching on or off processes, non-periodic sig- nals can be displayed and stored as long as required with constantly uniform screen intensity.
Influence on the lower frequencies After completion of HF compensation, check the signal hamfg on the screen at 1 MHz as well.
hamegg This lamp indicates by shining continu- ously that the memory mode is switched on. In addition, the input coupling switch or switches are set to GD. 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. 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.
Payment method Buyer protection on eBay Bank Deposit. Should the value marked with the arrow on the rear cover not agree with the existing mains voltage, the unit must be switched over according to the instructions on page M2.
The calibrator of the HM can even replace expensive square wave generators with these properties and gameg switchable frequency, e. This is caused by the loss of gain of the measuring amplifier. II input attenuator is pulled out. It goes out on triggering. The series impedance of the probe pro- vides a certain amount of protection for the vertical amplifier. When testing this connection or removing the CRT, pull the plastic coated clip left next to the screen out from the tube and discharge it against a side part of the chas- sis.
The Y signal can be inverted with the INV. X10 and the knob for the horizontal trace position X-POS.

When the memory mode is switched on, the analog timebase is switched off. In this case, special safety precautions are to be taken, which must be supervised by qualified per- sonnel if the voltage is higher than 42V. Switch over to the HF position for higher signal frequencies MHz.
However it should be noted that even above 50 kHz, a noticable phase difference between X and Y occurs and this increases with frequen- cies. The start of the pulse top is clearly visible with the X-MAG. Holding the casing firmly, pull out the chassis by the front panel molding. The latter must be switched over to x1 and its HF trimmer beneath the insulat- ing cap of the BNC plug set to the left stop. If condensed water exists in the instrument it should be acclimatized before switching on.
The two stored signal waveforms must be output in two plotting processes in the dual mode. In MONO mode display of the sum or difference depressed in addition of two signals. Flowever, purchase of the new FIAMEG scope tes- ter HZ 60, which despite its low price is highly suitable for tasks of this type, is very much recommended. This button should therefore be depressed only when required. LED flashes at incorrect timebase settings.
