General Power Meter Functions The following rules apply to naming sensor calibration tables: N O T E • The name must consist of no more than 12 characters. • All characters must be upper or lower case alphabetic characters, or numeric (0-9), or an underscore (_).
Page 71 General Power Meter Functions If you measure a signal with a frequency outside the frequency range defined in the N O T E frequency dependent offset table, the power meter uses the highest or lowest frequency point in the frequency dependent offset table to calculate the offset Selectable Frequency Dependent Offset Unit (dB or %) The offset in dB range is from –100 dB to +100 dB.
Page 72 General Power Meter Functions If the selected offset unit is %, the display of the offset will be in engineering unit only if the percentage value is less than 0.01% or more than 999%. The format of the display in engineering unit for an offset greater than 999% will be shown as follows, xxx.
Page 73: Setting Measurement Averaging
General Power Meter Functions Setting Measurement Averaging The power meter uses a digital filter to average power readings. The number of readings averaged can range from 1 to 1024. This filter is used to reduce noise, obtain the desired resolution and to reduce the jitter in the measurement results.
Page 74: Figure 2-15 Meas Avg Count Pop-Up
General Power Meter Functions Resolution is a measurement display function and not a channel function. In the case where a channel is set up in both the upper and lower window and the resolution settings are different, the highest resolution setting is taken to calculate the averaging number.
Page 75: Step Detection
General Power Meter Functions Step Detection To reduce the filter settling time after a significant step in the measured power the filter can be set to re- initialize upon detection of a step increase or decrease in the measured power. Step detection can be set in both manual and automatic measurement average modes.
Page 76: Measuring Pulsed Signals
General Power Meter Functions Measuring Pulsed Signals The power meter can be used to measure the power of a pulsed signal. The measurement result is a mathematical representation of the pulse power rather than an actual measurement (assumes constant peak power). The power meter measures the average power of the pulsed input signal and then divides the measurement result by the duty cycle value to obtain the pulse power reading.
Page 77: Figure 2-17 Duty Cycle Setting
General Power Meter Functions Procedure Set duty cycle as follows: 1 Press to display the Channel Setup screen. Confirm the channel requiring setup is displayed.

Page 78: Setting External Trigger For Average Power Measurement
General Power Meter Functions Setting External Trigger for Average Power Measurement There are two modes featured in triggered average power measurement • Power sweep mode • Frequency sweep mode These modes are used to eliminate the need for lengthy test routines, while increasing measurement throughput by reducing overhead of communication with the controller.
Page 79: Figure 2-19 Trig In And Trig Out Connection Diagram Between Power Meter And
General Power Meter Functions Power Sweep Mode Power sweep is generally used in power level calibration setup where the frequency is fixed (CW frequency), and the amplitude of the power source signal is swept. This mode can be used to characterize the flatness, linearity or gain compression of a device under test.
