RISETIME at NI SCOPE VS. SLOPE at NIDMM(Transmeas function)

Hello everyone.

Just want to ask the difference between Risetime value from NISCOPE to SLOPE value from NIDMM.

My project is to replace the use of NI SCOPE with our existing NIDMM 4070 in our capacitance test with fixed 13.5Volts and regulated current at 200mA. They have different response but connected in the same supply lines.

 See below..

 niScope_FetchWaveformMeasurement (ni5124_hdl, "0", NISCOPE_VAL_RISE_TIME, &p_oszi->RiseTime);

and

TransMeas(waveform,numSamplesAcquired,ANALYSIS_HIGH,1,90.0,50.0,10.0,PERCENTAGE_LEVEL,STATE_LEVELS_PEAK,1,&dSlope,&dDUration,&dStartTime,&dEndTime,&dLowRefValue,&dMidRefValue,&dHighRefValue,&dPreUnderShoot,&dPreOverShoot,&dPostUnderShoot,&dPostOverShoot);
