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 atten-
uation network has to be adjusted to the oscilloscope input circuitry, to guaran-
tee 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. This signal is available
at pin 3 of the 9 pin extension connector at the rear of the Handyscope HS6 DIFF.
Then adjust the probe for a square front corner on the square wave displayed.
