The maximum input voltage for the analog channels is 300 V RMS CAT II, which is equivalent to +51.8 dBm. However, this does not mean that you can apply this level of RF power to the oscilloscope without damaging tunnel rush. You need to consider the following factors:<br> <br> The frequency range of the oscilloscope is limited to the bandwidth of the analog channels, which is 200 MHz, 350 MHz, 500 MHz, 1 GHz, or 1.5 GHz, depending on the model. <br> <br> The input impedance of the oscilloscope is 1 MΩ, which is different from the standard 50 Ω impedance of most RF devices. <br> <br> The input coupling of the oscilloscope is either AC or DC, which affects the frequency response and the DC offset of the signal.
