    OLTS attenuation to give full available dynamic range from 1 V/div to 350 V/div for the ADP300, and from 200 mV/div to 350 V/div for the ADP305. Some of the transition of the scale factor will result in a change of attenuation.

  • Page 17: Smart Offset

    ADP30X Operator’s Manual Smart Offset The ADP30X has offset capability. This allows you to remove a DC bias voltage from the differential input signal while maintaining DC coupling. The offset range of the probe is a function of the oscilloscope’s sensitivity and the probe’s attenuation.

  • Page 18: Remote Control Commands

    REMOTE CONTROL COMMANDS Introduction When attached to a LeCroy oscilloscope equipped with ProBus interface, the ADP30X Active Differential Probe can be remotely controlled, along with the other oscilloscope functions. The control interface can be either the RS-232 or IEE-488 (GPIB) buses. The commands that control the probe are described below.

  • Page 19: Probe Auto Zero

    ADP30X Operator’s Manual Probe Auto Zero PRx:AUTOZERO, PRx:AZ Command Description The PRx:AUTOZERO command initiates an auto zero cycle in the ADP30X probe to remove any offset drift. The probe input can remain connected to the test circuit during the auto zero cycle.

  • Page 20: Probe Bandwidth Limit

    ADP300/305 Probe Probe Bandwidth Limit PRx:BANDWIDTH_LIMIT, PRx:BWL Command/Query Description The PRx:BANDWIDTH_LIMIT command sets the upper (HF) –3 dB bandwidth limit of the ADP305 probe. The arguments are in Hertz. Note The PRx:Bandwidth_Limit command is not available with model ADP300 The PRx:Bandwidth_Limit query returns the upper bandwidth limit setting for the differential probe connected to the specified channel.

  • Page 21: Probe Coupling

    ADP30X Operator’s Manual Probe Coupling PRx:COUPLING, PRx:CPL Command/query Description The PRx:COUPLING command selects the coupling mode of the ADP30X probe. The PRx:COUPLING? query returns the coupling mode of the selected channel.

  • Page 22: Probe Offset

    ADP300/305 Probe Probe Offset PRx:OFFSET, PRx:OFST Command/Query Description When an ADP30X probe is connected to a channel, the OFFSET command sets the probe offset value. The maximum range and resolution is determined by the V/DIV setting. If an out-of-range value is entered, the differential probe will set the offset to the closest valid value, and the VAB bit (bit 2) in the STB register will be set.

  • Page 24: Reference Information

    ADP300/305 Probe REFERENCE INFORMATION Differential Mode and Common Mode Differential amplifiers amplify the voltage difference that appears between the + input and – input. This voltage is referred to as the Differential Mode or Normal Mode voltage. The voltage component that is referenced to earth and is identical on both inputs is rejected by the amplifier.
  • Page 25 ADP30X Operator’s Manual The common mode frequency in these graphs is assumed to be sinusoidal. In real life applications, the common mode signal is seldom a pure sine wave. Signals with pulse wave shapes contain frequency components much higher than the repetition rate may suggest. As such, it is very difficult to predict actual performance in the application for CMRR versus frequency graphs.
