1、AP034-OM-E Rev DISSUED: January 2000? ? ? The following specifications are valid for model AP034 probes after the probe has reached operating temperature. This takes 20 minutes with power applied, in an environment with stable ambient temperature. The probe must be operating within the environmental

2、 conditions listed in the General Characteristics section, and must have been calibrated within the past 12 months in an ambient temperature of 23 5 C. NOMINAL CHARACTERISTICS Nominal characteristics describe parameters and attributes that are guaranteed by design, but do not have associated toleran

Add uncertainty of termination impedance to accuracy. 3 LeCroy measures CMRR with a fixture that connects the probe tip ground to the signal source ground. This method is necessary to obtain a reproducible

7、CMRR measurement. Often, users leave the probe tip ungrounded when measuring high frequency signals. Not grounding the probe tip can actually improve CMRR by allowing some of the common mode signal to be impressed across the entire length of the probe cable instead of from probe tip to probe ground.

8、 The CMRR improvement obtained without grounding the probe tip depends on proximity to probe cable ground; therefore, it is nonreproducible. LeCroy has chosen to use a reproducible method of measurement, rather than obtain a more optimistic measurement. RadioFans.CN 收音机爱 好者资料库 AP034-OM-E Rev DISSUED

EN 55011:1997:The probe has been tested to verify compliance with this standard, Class B for Conducted and Radiated Emissions. NE 500

16、82-1:1997:The probe has been tested to verify compliance with this standard for ESD, Radiated Immunity, EFT/Burst Immunity, Fast Surge Immunity, Conducted Immunity, and Voltage Sags however, probe offset can only be controlled through the buttons on the probe body. Also, the scale factor will be displayed incorrectly in some modes.
