2. Set the HP 3457A to the AC Voltage function (ACV), the range to 300 mV and the AC Bandwidth
to AC Fast. (To change the Bandwidth - Press the SHIFT key, then the Configuration A key, Use the J
scroll key to display ACBAND. Enter a number greater than 400 and press the ENT key).
3. Use the Test Record to record the 30 mV (300 mV tenth-scale) readings at 400 Hz, 6.5 KHz,
20 KHz, 100 KHz, 300 KHz and | MHz
4. Set the AC Voltage Standard for an output voltage of 300 mV.
5. Use the Test Record to record the 300 mV readings at | MHz, 300 KHz, 100 KHz, 20 KHz, 6.5 KHz
and 400 Hz.
