High Speed Sinusoidal Jitter Calibration
Purpose and Method
This procedure calibrates the Sinusoidal Jitter (SJSWEEP) at TP1.
For this purpose, use the EZJIT+ application on the real-time scope. The
test automation starts by applying small SJ amplitudes and increases the
amplitude levels. For every set RJ value, the corresponding amplitude is
measured.
This calibration is only available for HBR3 data rates. It must be repeated
for different frequencies: 500KHz, 1MHz, 2MHz, 10MHz, 20MHz and
100MHz.
