Testing method
• Wait for 30 minutes after the TA320 is turned ON.
• Set the frequency of the synthesized signal generator (8657B) to the values given in the table
below, and check that the measured values (mean value and standard deviation) are within the
allowable range using the the pulse width function of the TA320. Carry out the same test for
both channels CHA and CHB.
