Sweep Output; Leveled Sine Output With Offset - Fluke 9640A Series Instruction Manual

9640A
Instruction Manual

Sweep Output

Requirement: To perform a single sweep from 1 MHz to 10 MHz in 1 MHz steps with
133 ms between each step at 1V rms.
Requirement: To perform a repetitive logarithmic sweep of 15 points over 20 MHz,
centered around 100 MHz with a dwell of 1 second between each step, started by an
external trigger.

Leveled Sine Output With Offset

Requirement: To output a 1.1 MHz, -14.2 dBm sine wave. Then to offset the output
power by +0.1dbm
Requirement: To find out what the UUT error is in the above scenario.
