— 2x 10:1 probe PM8926/09, incl. * spring-loaded test clip
* earth cable
'— Instruction card
@ INTRODUCTION
The PM8936/09 is a 10x attenuator modular probe with automatic range indication possibility, designed
for oscilloscopes. The cable length is 1,5 m. At delivery the probe has been adjusted to an oscilloscope
with an input capacitance of 20 pF.
@® CHARACTERISTICS
— Attenuation (d.c.) 10x
— Bandwidth d.c...200 MHz (—3 dB)
— Useful system bandwidth d.c...100 MHz (—3 dB)
— Input resistance at d.c. 10 MQ +or— 1,5 %
— Input capacitance at d.c. 13,5 pF
~— Compensation range 5 pF....40 pF
— Max. non destructive input voltage 500 V
(d.c. + a.c. peak) at d.c.
® DISMANTLING
* The probe body can be removed by sliding the probe body from the cable assembly.
* The compensation box can be slid off the cable assy after the knurled nut has been unscrewed in a counter
clockwise direction,
* To expose the h.f. adjustment controls the terminating box cover can be slid off the compensation box.
@ ADJUSTMENTS
Matching the probe to the oscilloscope:
Connect the probe to the CAL socket of the oscilloscope.
A trimmer can be adjusted for the |.f. response through a hole in the compensation box to obtain optimum
square-wave response.
