System Specifications and Characteristics
The video bandwidth in the meter can be set to High, Medium, Low and Off. The video bandwidths stated in the table below are not the
3 dB bandwidths, as the video bandwidths are corrected for optimal flatness (except the Off filter). Refer to Figure 2 for information on
the flatness response. The Off video bandwidth setting provides the warranted rise time and fall time specification and is the recom-
mended setting for minimizing overshoot on pulse signals.

Recorder output and video output
The recorder output is used to output the corresponding voltage for the measurement a user sets on the Upper/Lower
window of the power meter.
The video output is the direct signal output detected by the sensor diode, with no correction applied. The video output provides a DC
voltage proportional to the measured input power through a BNC connector on the rear panel. The DC voltage can be displayed on an
oscilloscope for time measurement. This option replaces the recorder output on the rear panel. The video output impedance is 50 ohm.
