Here I will post my first use experiences and impressions of my new MSOX3054A.
1/ Attaching a probe (unadjusted) to channel 1 and measuring the probe comp 1 output.
Snapshot output figures (Amplitude only-Frequency=1.0012KHz)
Pk-Pk 2.65v
Max 2.54v
Min -120 mV
Ampl 2.51v
Top 2.49v
Base -30mv
Over 2.0%
Pre 2.0%
Avg-Cyc 1.2167v
Avg-FS 1.2167v
DC-RMS Cyc 1.75v
DC-RMS Fs 1.75v
AC-RMS Cyc 1.2564v
AC-RMS Fs 1.2561v
Measurements on probe comp 1 pin with a GM Metrahit XTRA
DC voltage 1.215v
AC voltage (1M Ohm setting) 1.225v
Measurements with built in DVM
AC RMS 1.26v
DC 1.22v
DC RMS 1.75v
What strikes me is the difference in RMS measurement values between the inbuilt DVM, my multimeter and the scope measurements. The scope measurements are done with an uncompensated scope and there is some pre/over shoot present on the waveform.
More observations later.
David.
