When measuring DC signals, make sure to set the signal
coupling of the input to DC.
3.5 Probe compensation
The Handyscope HS5 is shipped with a probe for each input chan-
nel. These are 1x/10x selectable passive probes. This means that
the input signal is passed through directly or 10 times attenuated.
When using an oscilloscope probe in 1:1 the setting, the
bandwidth of the probe is only 6 MHz. The full bandwidth
of the probe is only obtained in the 1:10 setting
The x10 attenuation is achieved by means of an attenuation
network. This attenuation network has to be adjusted to the oscil-
loscope input circuitry, to guarantee frequency independency. This
is called the low frequency compensation. Each time a probe is
used on an other channel or an other oscilloscope, the probe must
be adjusted.
Therefore the probe is equiped with a setscrew, with which the
parallel capacity of the attenuation network can be altered. To
adjust the probe, switch the probe to the x10 and attach the probe
to a 1 kHz square wave signal. Then adjust the probe for a square
front corner on the square wave displayed. See also the following
illustrations.
