VVM (Vector Voltmeter) Mode - Option 308
VVM Mode Settings
Display Resolution
You can display either one digit or two digits after the decimal point for both
magnitude and phase readings.
This setting survives a Preset and Mode Preset.
How to set Resolution
—Press Scale/Amptd .
—Then Resolution
.
—Then choose:
— 1
0.0 (default)
— 2
0.00
IF Bandwidth
Reducing the IF receiver bandwidth reduces the effect of random noise on a
measurement. However, narrower IF bandwidths cause longer measurement
times.
For highest accuracy, Zero AFTER changing the IF Bandwidth. Learn about
“Zeroing” on page 14-8.
How to set IF BW
—Press BW 2.
—Then IF BW
.
— Then choose from the following:
— 300 Hz
| 1 kHz | 3 kHz | 10 kHz | 30 kHz
Output Power
Set the power level out of the FieldFox to High, Low, or manually set power
level to a value between High and Low.
Generally, the high power setting is used when measuring passive, high-loss
devices to place the signal farther from the noise floor. However, for devices
that are sensitive to high power levels such as amplifiers, use the Low power
setting.
