Very often hum is present on the signals under test. This can be easily determined from the screen because the hum is related to the line frequency. If a signal shows a kind of unexpected...

While measuring complex waveforms in digital techniques, mistakes can be made very easily. In this section, examples of this are presented. Some of them are explained in detail, to gain knowledge about the possible reasons...

PULSE DEFINITIONS In digital techniques, it can happen that two pulses appear in a timerelated sequence, but that the second pulse appears a little later, with a delay, with respect to the first one. If...

CURRENT PROBES Basically, the current probe is a transformer of which the primary winding is the test lead through which the current is measured. The probe head consists of a ferrox-cube core and the secondary...

Terminated HF Probes At higher frequencies, the input capacitance has much less impedance (Xe) than the 10- or 20-MO input resistance of the probe. For the circuit under test, this means that if the internal...

A plug-in oscilloscope is electrically like any other oscilloscope. The mechanical housing of the plug-in instrument is different from that of the compact one, because the former consists of a mainframe to which one or...

The delayed time base is started (or triggered) when the MTB sweep has reached a certain level, which is compared to a preset dc level. The preset level is thus reached a certain time after...

TTL Triggering In logic systems employing building blocks (gates, Aip-Aop, etc.), a logic state level may be defined to determine whether a logic signal is supposed to be in its 0 (zero) or in its...
