Operating Basics
Please followthese operating guidelines to get optimum performance
from your P7240 probe.

Handling the Probe

Exercise care when using and storing the P7240. The probe and ca ble
are susceptible to damage caused by careless use. Always handle the
probe using the compensation box and probe head, avoiding undue
physical strain to the probe cable, such as kinking, excessive
bending, or pulling. Visible dents in the cable will increase signal
aberrations. Do not drop the probe or subject it to physical shock.
Damage to the probemay result.

Maximum Nondestructive Input Voltage

The P7240 is electrically protected a gainst static voltage; however,
applying voltages above its design limits may damage the probe tip
amplifier.Refer to Specifications on page 23 for the maxim um
operating voltage and frequency derati ng information.

Input Linear Dynamic Range

The probe head amplifier used by the P7240 has a limited linear
operating range. To keep the input linearity error l esstha n 1.0%, you
must limit the apparentsignal input voltage t o ±2.0 V.
Use the DCoffset adjustment to maintain the probewithin its
dynamic range. The nominal offset adjustment range of the P7240 is
±5.0 VDC.
NOTE. The probe can tolerate input voltages of ±30 V without
damage;however, the linearity errorspecification does not apply to
input voltages exceeding ±7.0 V (including any DC offset). See
Figure 4 on page 16.
