Power Supply Noise Injector

In some applications, the device under test may be sensitive to power supply
noise. For example, VCO (voltage controlled oscillator) phase noise may be
degraded with excessive supply noise. The TS200 can be used to aid supply
noise sensitive circuit testing.
Figure 10 shows a supply noise simulation setup. The function generator is set
to noise output. The function generator output is connected to the TS200 Mod
input. The input is set to AC-couple. Adjust the DC Offset knob until the
TS200 output voltage reaches the desired DUT supply voltage level. Adjust the
noise level on the function generator to see how the DUT is responded to
supply noise.
