Basic operation
Probe offset
The probe offset is adjustable for operation within the linear range of the probe, and to increase the sensitivity of the probe at
higher DC measurement voltages. Using the offset to cancel DC signal components enables optimal probe performance.
(See Figure 2 on page 6.)
NOTE. See your oscilloscope manual for speci fi c instructions on using the offset control.
To set the probe offset, follow these steps:
1. Set the probe offset equal to the expected nominal DC value of the source you are connecting to.
2. Set the vertical scale to 500 mV/div.
3. Connect the probe to the circuit.
4. Change the volts/div setting to the desired range, adjusting the offset as needed to keep the signal in the center of
the screen.
The probe has a ±60 V offset range. The linear operating range is ±1 V. (See Figure 2 on page 6.) When you adjust the
probe offset with no signal applied to the probe input, the output range is ±1 V, (the linear operating range of the probe),
not the ±60 V offset range of the probe. However, when you apply up to ±60 V to the probe input, the probe offset control
can zero this offset.
NOTE. If the signal on the screen displays an offset that is either 1 Volt higher or lower than expected, check to make sure
the DUT is connected and operating. This is a result of the input to the LF ampli fi er being clamped at one extreme of
the dynamic range when no input is present.
Connect MMCX accessories
Gently insert the MMCX end of the cable into one of the following accessories: micro-coax tip, solder fl ex tip, u. fl adapter or
MMCX to square pin Y-lead adapter, until you feel the connector engage. To remove an accessory, gently pull from the
MMCX connection point, being careful to only grip the knurled metal area of the connector.
Connect solder-in accessories
Micro-coax tip.
For convenient fi rst-time use, the solder micro-coax tips are shipped pre-trimmed and ready to be
soldered to the test point. You can reuse a tip by removing the tip from the solder joint and then trimming the wire insulation
back to expose the center pin and ground shield on the tip cable.
