Pulse Modulation

signal generator’s source match by inserting 

10 

 attenuation and

using a 10 

 higher ALC level.

Video Feedt hrough

Video feedthrough is a video signal at the modulation rate that is
superimposed on the RF envelope (see Figure M-6). If large enough,
video feedthrough can disturb mixer balance, amplifier bias, crystal
detector output, etc. Because it is low frequency energy, it can
disturb systems that are not intended to deal with it, especially
demodulation systems. High band 

 

 employs a tracking

YIG filter that essentially eliminates video feedthrough except in
Option 006 (b

the pulse modulator is after the YIG filter).

Attempts to measure high band video feedthrough can turn out to
be measurements of ground currents in coaxial cables. Low band

 

 employs a low-level mixer followed by a high gain

amplifier. At high power levels 

 -10 

 the bias levels in the

amplifier shift slightly as the RF is turned on or off. The slew of the
bias from one level to another couples to the output and produces
the video feedthrough waveform. At low ALC levels (-10 
another mechanism dominates. Mixer imbalance produces DC at the
output of the mixer, and its magnitude varies with RF amplitude and
modulator state. This shifting DC level couples through the amplifier
as video feedthrough spikes. In percentage terms, this mechanism

gets worse at low levels.

Slow Rise Time Pulse Modulation for Scalar Network Analyzers

For use with Hewlett-Packard scalar analyzers, the swept signal

generator offers a scalar pulse modulation mode that provides
approximately 2 

 rise and fall times. An internal oscillator

provides the 27.778 

 square wave with no external connections

necessary. The slow waveform reduces the spectral width of the
output, improving measurements made on filters with steep skirts. A
slow pulse rise time (approximately 2 

 is available for externally

generated pulse inputs as well.
