Probes
The 222PS comes with two P850 10X probes. An additional 1X probe,
the P400 probe, is available as an optional accessory.
The P850 probes provide high attenuation so that you can scale
signals approaching 600 VAC
RMS
for better display. They are also
useful for measuring sensitive highĆimpedance electronic circuits or
highĆvoltage divider circuits. The optional P400 probes measure
lowĆlevel signals requiring high sensitivity.
CAUTION
To prevent improper operation and the risk of electric
shock, use onlyTektronix P400 or P850 probes with this
instrument.
Actual probe attenuation factors are 3X for the P400 probe
and 30X for the P850 probe. The instrument is calibrated to
compensate for these attenuation factors. Other probes or
input devices will therefore give incorrect amplitude
displays.
The optional P400 1X probe limits the maximum deflection factor of the
222PS to 50Ăvolts per division. It decreases the probe tip input impedĆ
ance to 1ĂM W and is sufficient for minimal loading of sensitive circuits.
The P400 probe also limits input frequency to 20 MHz.
WARNING
To avoid personal injuryor damage to the 222PS or the
probes, do not applymore than 850ĂV peak between
probe tip and earth ground, between probe tip and probe
common, or between probe common and earth ground.
