24. nge of the equipment Model 7002 003 and Model 7002 005 The EMPower USB RF Power Sensor uses a high performance demodulating logarithmic amplifier to detect the RF signal The demodulated signal is sampled at high speed by a powerful DSP which processes all samples The burst pulse versions of the EMPower sensors 7002 003 and 7002 005 support these four modes of operation Note Only in RMS mode can a sampling speed of 10 Msps be used The maximum sampling speed in all other modes is 1 Msps MODE 0 RMS POVER Mode 0 is used to perform RMS power measurements of CW signals In RMS mode the EMPower sensor samples the demodulated signal at high speed up to a maximum of 10 Msps The RMS value of the power is calculated over the number of samples defined by the filter setting and can be read by a simple command Due the high sampling speed the number of readings is high even at large filter settings MODE 1 PEAK POWER Mode 1 is used to perform peak measurements on RF signals In peak mode the EMPower sensor keeps track of the highest level which has been detected This can be done for an infinite time Once the power level has been read the maximum value is automatically reset www ets lindgren com Operation 21 MODE 2 ENVELOPE TRACING Mode 2 is used to capture the envelope of an RF signal Envelope tracing is a unique feature which enables the possibility to visualize for example the in rush phenomena of transmitters or sig
