It is recommended when checking the operating voltages also to check their hum or interference voltages. 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.

The series impedance of the probe pro- vides a certain amount of protection for the vertical amplifier. Immediately after unpacking, the instrument should be checked for mechanical damage and loose parts in the interior. Short rise time, horizontal pulse tops, calibrated pulse height and zero potential at the pulse bottom are essential for exact attenuator probe cali- bration.

The square wave signal can be taken from the two concentric sockets beneath the screen. Select a valid country. For this purpose, select with the 2. Intermediate values can be set with the small concentric knob variable.

The limit frequencies depend upon the signal height adjusted with internal triggering. This damage the phosphor of the tube if set too bright. The clear advantage over ordinary probes are field replaceable parts and the HF-compensation feature on the 1 0: If the signal frequency is not known, there are two other methods for correct time coefficient setting. Standard attenuator probes on the oscilloscope normally reduce its bandwidth and increase the hsmeg time.


It is important that the sequence of firstly 1 kHz and then 1 MHz hsmeg must be followed but need not be repeated, also calibrator frequencies of 1 kHz and 1 MHz cannot be used for time calibration. When the memory mode is switched on, the analog timebase is switched off. Feb 26, The post-acceleration connection of the CRT remains at a high voltage even a lengthy time after switching off.

Bidding has ended on this item. This is hsmeg only way to produce an extremely short ground connection which bameg essential for high signal frequencies and an unadulterated wave form display of non-sinusoidal signals.

As a result of intermediate storage, the reduction of trace brightness, normally observed at higher fre- quencies, bameg avoided. M6 Subject to change without notice With all attenuator probes, the maximum AC input volt- age must be deratedwitb frequency usually above 20 kHz.

For sine wave signals the upper limit is approx 30 Hwmeg. Button depressed – internal triggering from Channel II. There are 0 items available. For higher frequencies, the signal source must be of low impedance, i. It is possible to work with automatic triggering here.

A capacitor of corresponding capaci- tance and voltage rating may be connected in series with the attenuator probe input for blocking DC voltage e. Scanning and storage start at this instant. If it is necessary to employ the full dot density of Channel I alone, two buttons 2.

Particular care is required with a stationary dot. For additional information, see the Global Shipping Program terms and conditions – opens in a new window or tab This amount includes applicable customs duties, taxes, brokerage and other fees.


Its purpose is to join a stored sequence of points by bright lines.

One socket supplies 0. Therefore C should be suffi- ciently large and produce only a relatively small just observable phase shift. Operating voltages Apart from the two a. The seller will not accept returns for this item.

Practically every early failure is detected in intermittent operation by this. Regulated DC power supplies: Here it must be noted that the terminating resis- tor HZ 22 will only dissipate a maximum of 2 Watts. Should the waveform held in store 1 and store 2 need to be plotted, take care not to release the HOLD buttons when using the 2. A bright dot simultaneously traces the plot on the screen of the HM The “case history” of the signal before and after the trig- ger point is now visible.

Switch test signal coupling to AC or DC. Therefore a functional guarantee of 2 years is given for all units.

Lights up on triggering. It should be noted that slight distor- tion of the signal shape, especially of non-sinusoidal signals is unavoidable when this button is depressed.

The same volt- age attenuation then results at high and low frequencies as for direct voltage for x1 probes or probes switches over to x1, this compensation is neither necessary nor possible.

As already described, in the analog real time mode of the HMall numerical values printed on the time switch scale can also be set for the time coefficients. Image not available Photos not available for this variation.
