Channel I and II: Learn Uameg – opens in a new window or tab Any international shipping is paid in part to Pitney Bowes Inc. All values to be measured can therefore be determined relatively accu- rately but it should be remembered that from approximately 6 MHz upwards the vertical measuring error will increase constantly with increasing frequency.

Correction of a few degrees is pos- sible by turning a potentiometer behind an opening on the front panel marked with TR using a small screw driver.
As in the real time mode, the phase difference of two synchronous sig- nals of the same hamey and shape can be measured on the screen see page Ml 2. The triggering range covered with the LEVEL control is highly dependent on the amplitude of the signal displayed. Especially when transmitting square and pulse signals, a resistor equal to the characteristic impedance of the cable must also be connected across the cable directly at the Y- input of the oscilloscope.
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.
Setting triggering with hamef aid of a simulated signal is recommended under certain circumstances.
Because of the limited scanning rate, other limits which are further influ- enced by signal shape and screen amplitude apply in the digital memory mode. Conversely multiply sine wave voltages stated in Vrmg by 2. Insert probe in 0. Haeg compensation trim- mer must now be adjusted. Section beneath the screen: It can be easily operated after remov- ing the casing see servicing instructions.
20 includes the following: To produce a stationary display, triggering must be synchronous with the test signal. They are a hazard to life.

Connect probes of the type HZ5152 or 54 to the CH. It goes out on triggering.
Firstly the fuse holder printed with the voltage values is removed using a small screw driver and – if required – provided with another fuse. If the HOLD I button is now depressed, the signal displayed at the moment of depressing is “frozen” and therefore permanently stored.
Stored waveforms may be recorded using a chart- or X-Y recorder. It goes out at the instant of triggering. Transport damages are not covered by the guarantee.
However, there are still further display modes in the mem- ory mode: Back to eBay Home. If the adjacent Each signal change is immediately detected. Whenever it is likely that protection has been impaired, the instrument shall be made inoperative and be secured against any unintended operation. However, the load on a supply could become open circuited on a defective unit causing the supply capacitors to remain charged. Other components are connected by using 2 banana jacks.
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. Damages arising because of this are not covered by the guarantee. However, in the memory mode much larger time coefficients are required to overcome the flic- kering or creeping of a light dot at very low signal frequency unavoidable in real time mode. In return, however, the read out, visible image appears immediately after the single sweep ends.
Nor- mally the capacitors are discharged 6 seconds after switching off.
Influence on the medium frequencies T4: Memory modes see M 1 6 ff. In this way transient distortions such as overshooting, rounding off, ringing, holes or humps in the pulse top in the vicinity of the leading edge are kept to a minimum. Operating modes of the vertical amplifiers The desired operating mode of the vertical amplifiers is selected mh the 4 buttons in the Y field.
