Test procedure
1 Turn on the E8257D, oscilloscope, and 8990B.
2 Allow the system to warm up for approximately an hour before starting the
3 Generate an RF pulse signal from the E8257D with the following

measurement.
recommended signal profile:
– Frequency: 1 GHz
– Power level: 10 dBm
– Pulse period: 10 μs
– Duty cycle: 50%
The pulse signal is characterized using a diode detector which feeds to the
oscilloscope. This is to verify that the rise/fall time of the RF pulse measured by
the oscilloscope is <5 ns and the overshoot is <0.5%.
