The highest resolution and simplest operation is obtained if the two signals are read into the memory consecutively through Channel I.

Therefore a functional guarantee of 2 years is given for all units. In hakeg 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. Single, X-Y operation, addition: The protec- tive hamrg must not be negated by the use of an extension cord without a protective conductor. It can be switched over to other voltages at the fuse holder combined with the 3-pole appliance inlet at the rear of the instrument.

Trace rotation TR Despite Mu-metal shielding of the CRT effects of the earth’s magnetic field on the horizontal trace position cannot be entirely avoided.

In MONO mode display of the sum or difference depressed in addition of two signals. DC to at least 40 MHz. The display of simple electrical pro- cesses, such as sinusoidal RF and LF signals or mains fre- quency hum voltages is straightforward.

The pulse duty factor also deviates from the value 1: The larger output speed is always towards the rear of the casing. The trigger LED stays lit for approximately ms for each trigger pulse detected. Input impedance 1 MQ ll30pF. Search the history of over billion web pages on the Internet. Intermediate values can be set with the small concentric knob variable. If it is a question of pulses of the same shape, read off at steep edges.

The repeti- tion frequency of the signal must therefore be significantly smaller than the upper limit frequency of the vertical amplifier. However, the visible signal on the screen can be expanded by pressing the X-MAG. However, the load on a supply could become open circuited on a defective unit causing the supply capacitors to remain charged.

Then replace the fuse holder so that the impressed white triangle points to the desired mains voltage. The trace line must be parallel with the horizontal graticule lines see “Trace rotation TR”, page M8. Ask a question – opens in a new window or tab. It is possible to work with automatic triggering here. It should be noted that slight distor- tion of the signal shape, especially of non-sinusoidal signals is unavoidable when this button is depressed.

A particulartimebase setting suits each input signal frequency.

Safety Class I with safety earth conductor; not in safety class II. Will usually post within 3 business days of receiving cleared payment – opens in a new window or tab. Memory mode See memory mode operating instruction page M 1 5.

Athe handle is pulled sideways slanting upwards after putting the instrument down and then engaged in the desired posi- tion with turning and following pressure. The present instruction manual contains important information and hhameg which have to be fol- lowed by the user to ensure safe operation and to retain the oscilloscope in safe condition.

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. However, normal trigger- ing with suitable LEVEL adjustment is more favourable because the trigger point on the signal is determined in this case. If a x1 0 or x1 00 attenuator probe is used, no hn is necessary. Therefore the derating curve of the attenuator probe type concerned must be taken into account.

It is 028 of the position of the INV. It is further pointed out that short circuits at different points in the CRT 280 circuit may result in the simultaneous failure of various semi-conductors and or the optocoupler.

Trigger signal inputto TRIG. Center trace on screen using the Y-POS.

A suitable trigger edge arriving after hammeg of the pushbutton initiates the single sweep. At the left stop, the time coefficient set on the switch in analog mode is at least 2. Standard attenuator probes on the oscilloscope normally hamge its bandwidth and increase the rise time.

Stored waveforms may be recorded using a chart- or X-Y recorder. Here it must be noted that the terminating resis- tor HZ 22 will only dissipate a maximum of 2 Watts. Power consumption; approx 46 Watts.

The Y signal can be inverted with the INV.
