Output Frequency:

The frequency setting or the inverse of the

period setting.

Current:

The instantaneous output current.

Peak Current:

The amplitude of the output current signal. The GLX

computes Current by taking half of the difference between the maxi-
mum and minimum currents measured over the previous cycle of oscil-
lation. Note that Peak Current is not necessarily equal to maximum
output current. This measurement is not meaningful when the waveform
is set to DC. The sampling rate of the Current measurement must be at
least 1 Hz for the Peak Current measurement to work.

To Record Measurements

1.

Press

. The GLX starts recording data at the specified sampling

rate for each measurement.

2.

Press

again to stop recording.

To Display a Measurement

1.

Open the Graph, Table, Digits, or Meter screen.

Note: If you are operating in the Graph screen with the Power Amp panel visible,
you may need to press

to switch activity to the Graph before proceeding.

2.

Press

to light up the active fields.

3.

Use the arrow keys to navigate to measurement name field on the
axis, column, or segment where the measurement is to be displayed.

4.

Press

. A menu opens.

5.

Use the arrow keys to highlight the desired measurement and press

.

To Change the Sampling Rate

As with other sensors, the Power Amplifier’s measurements are config-
ured in the Sensors screen. The four measurements appear there as four
separate virtual sensors. The sampling rate of each virtual sensor is set
separately.

1.

Press

+

to open the Sensors screen.

2.

Use the left and right arrow keys to select a virtual sensor.

3.

Press

to change the Sample Rate Unit setting to samples/s (for

rates faster than once per second) or to seconds, minutes or hours
(for slower rates).

4.

Press the down arrow key to highlight Sample Rate.

5.

Press

or

to increase or decrease the rate or time between

samples.
