METER Measure the frequency of the input signal in

Meter mode.

Hz

SCOPE Measure the frequency of the waveform in

Scope mode. At least 11/2 cycles of this waveform must occur between the cursors.

duty cycle + METER Measure the ratio between the time the signal is positive to the total period time in Meter mode. It is shown as a percentage figure.

duty cycle - METER Measure the ratio between the time the signal is negative to the total period time in Meter mode. It is shown as a percentage figure.

pulse width + METER Measure the duration of the average positive pulse of the waveform in Meter mode.

pulse width - METER Measure the duration of the average negative pulse of the waveform in Meter mode.

dBm DC METER (decibel milliwatt) Measure the power ratio of the DC component of a signal with respect to 1 mW in Meter mode. This is done with DC-coupled input.

You can choose 50, 60, 75, 93, 110, 125, 135, 150, 250, 300, 500, 600, 800, 900, 1000, or 1200as reference impedance.

dBm AC METER (decibel milliwatt) Measure the power ratio of the AC component of a signal with respect to 1 mW in Meter mode. This is done with DC-coupled input. You can choose 50, 60, 75, 93, 110, 125, 135, 150, 250, 300, 500, 600, 800, 900, 1000, or 1200as reference impedance.

dBW DC METER (decibel Watt) Measure the power ratio of the DC component of a signal with respect to 1W in Meter mode. This is done with DC-coupled input. You can choose 1, 2, 4, 8, 16, or 50as reference impedance.

dBW AC METER (decibel Watt) Measure the power ratio of the AC component of a signal with respect to 1W in Meter mode. This is done with DC-coupled input. You can choose 1, 2, 4, 8, 16, or 50as reference impedance.

WATT DC METER Measure the DC audio watts from the signal in Meter mode. This is done with DC-coupled input. You can choose 1, 2, 4, 8, 16, or 50as reference impedance.

WATT AC METER Measure the AC audio watts from the signal in Meter mode. This is done with DC-coupled input. You can choose 1, 2, 4, 8, 16, or 50as reference impedance.
