The E9323A/E9327A Peak Power Sensors have a 5-MHz video bandwidth
, and the dynamic range covers -32 dBm to +20 dBm.
The generator output was measured by an Agilent EPM-P Series Single-Channel E4416A Power Meter and an E9327A Sensor with 5-MHz video bandwidth
. The default acquisition conditions for this power meter ensure a 10-ms capture time at a 20-MS/s continuous sampling rate.
Typical examples include a limiter or post-limiting bandpass filter, and a log video amplifier to provide log video output, selectable video bandwidth
, and RF, video or digital outputs.
is the measure of the envelope speed that the sensor and meter can track.
The analog path comprises a downconverter, IF filter (resolution bandwidth), IF amplifier, detector and video bandwidth
A peak power video bandwidth
of at least 1 MHz is required to characterize the profile of such a digitally modulated pulse.
The log-scaled signal strength output from each RBW is passed thru a computer-controlled multiplexer (MUX) and on to the programmable video bandwidth
Another inconsistency is that many international specifications state that the spectrum analyzer should respond to the sum of all power within the channel bandwidth, while at the same time requiring that the video bandwidth
be equal to the resolution bandwidth.
The noise level also is acceptable using a wider, 100 kHz resolution in conjunction with a narrow video bandwidth
. However, testing and/or calculation shows that sweep time is somewhat greater at the wider resolution and narrow video bandwidth
This unit has a dynamic range of 45 to 50 dB, a -41 dBm TSS and a typical video bandwidth
of 70 to 80 Mhz.
