Nevertheless, RF performance has not been sacrificed as is evident from typical values of -163-dBm DANL, -105-dBc phase noise (1 Hz) at 100-kHz offset (10 MHz to 3 GHz carrier), and 0.5dB amplitude uncertainty.
The displayed average noise level (DANL) of a selected RBW relative to the noise associated with a 1-Hz bandwidth is given by
(DANL), great selectivity, and stability over time."
Agilent's M9393A VSA (Figure 1) features 0.15-dB absolute amplitude accuracy,-160-dBm DANL. and analysis bandwidth of 40,100, or 160 MHz.
The displayed average noise level (DANL) specification for a spectrum analyzer is given in units of dBm/Hz.
-140 dBm DANL spectrum-analyzer performance, and optional through-line power meter operation.
It enhances compliance testing with measurement accuracy of [+ or -]0.75 dB at 1 GHz, high sensitivity with a DANL of -167 dBm at I GHz, and a frequency range of 20 Hz up to 26.5 GHz.
The low DANL of -164 dBm/Hz in the microwave range with activated preamplifier allows even the smallest of spurious emissions to be detected--such as those found in radar signals.
Features include a typical -152-dBm DANL; [+ or -] 0.1 ppm annual aging rate, which reduces frequency drift; one-button PowerSuite operation (CHR OBW, ACPR, SEM, and spectrogram), which makes power measurements and signal monitoring simple and intuitive; an optional 7-GHz tracking generator with a built-in VSWR bridge, which supports transmission and reflection measurements; a demodulation mode to easily and cost-effectively gain more insight into AM, FM, ASK, and FSK signal analysis; and user-definable soft keys, which provide access to seven of the most frequently used measurement setups.
