TEKTRONIX DSA70404C 4 Ch 4 GHz Digital Serial Analyzer

The Tektronix DSA70404C with 4 analog channels has a high signal-to-noise ratio and low internal noise floor. It allows you to find the smallest anomalies affecting the DUT's performance. Bandwidth enhancement eliminates imperfections in frequency response all the way to the probe tip. User-selectable filters for each channel provide magnitude and phase correction for more accurate representation of extremely fast signals. 
Specifications.

Carrier Wave (CW)
Carrier Wave or Continuous Wave is a sinusoidal signal without modulation.

Harmonic
A harmonic of a wave is a component frequency of the signal that is an integer multiple of the fundamental frequency, i.e. if the fundamental frequency is f, the harmonics have frequencies 2f, 3f, 4f, . . . etc.

Noise Floor
Noise floor is the measure of the signal created from the sum of all the noise sources and unwanted signals within a measurement system.

Ripple
Ripple is the small unwanted residual periodic variation of the direct current (dc) output
