System Specifications and Characteristics
Average power measurement accuracy
N1923A
≤ ± 0.2 dB or ± 4.5% ¹
N1924A
≤ ± 0.3 dB or ± 6.7%
1.  Specification is valid over a range of –15 to +20 dBm, and a frequency range of 0.5 to 10 GHz, DUT Max. SWR < 1.27 for the N1923A, and a frequency range
of 0.5 to 40 GHz, DUT Max. SWR < 1.2 for the N1924A. Averaging is set to 32.
Video bandwidth
The video bandwidth in the peak power
analyzer 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 1 for information
on the flatness response. The Off video
bandwidth setting provides the warranted
rise time and fall time specification and is
the recommended setting for minimizing
overshoot on pulse signals.
