• RF measurements should be done with a Spectrum Analyzer and a high-frequency
500 ohm passive probe, for example HP54006A. (Note that when measuring with the
500 ohm probe the signal will be around 20 dB attenuated. The values in the following
will have these 20 dB subtracted and represent the real value seen on the spectrum
analyzer).
• LF (Low frequency) and DC measurements should be done with a 10:1 probe and an
oscilloscope. The probe used in the following is 10MΩ/8pF passive probe. If using
another probe then bear in mind that the voltages displayed may be slightly different.
