rf spectrum analyzer reading high gain with no input This is nowhere near the damage level of my power sensor (or spectrum analyzer of +20 dBm (100 mW)). So you see, the output of the HT is +37 dBm and the best coupling with the antenna stuck in the end on the N connector gives -2.2 dBm.

Enough attenuation will attenuate your noise down to -174dBm/Hz (at 290K). The spectrum analzyer's attenuator causes an internal increase in gain at the IF stage after the . Relative readings are the mid ground where you can decide if the gain of a stage is not as expected. If you have the same of lower signal level at the output of an MMIC gain block amplifier as that at its input, then there is likely something very wrong with that stage !

This information will help you buy the perfect spectrum analyzer for your needs. This is nowhere near the damage level of my power sensor (or spectrum analyzer of +20 dBm (100 mW)). So you see, the output of the HT is +37 dBm and the best coupling with the antenna stuck in the end on the N connector gives -2.2 dBm. Enough attenuation will attenuate your noise down to -174dBm/Hz (at 290K). The spectrum analzyer's attenuator causes an internal increase in gain at the IF stage after the mixer and amplifies the device's noise floor (regardless of the input).

Learning Objectives. Name the major measurement strengths of a swept-tuned spectrum analyzer. Explain the importance of frequency resolution, sensitivity, and dynamic range in making analyzer measurements. Outline the procedure making accurate distortion measurements. As with the sample detector, an average detector can show too low a reading for the amplitude of a CW signal if the RBW is set too narrow. A normal detector, in most cases, is the default detector for a spectrum analyzer.If the input level is too high, these devices can go into compression, which creates distortion and negatively effects the measurement results, sometimes very severely. To prevent this from happening, a variable input attenuator is placed between the .
What does the attenuation setting do in an RF spectrum analyzer?
Spectrum analyzers are designed for linearity and have miserable noise figures - 30 to 40 dB is not untypical. You can improve the sensitivity by a low noise high gain preamplifier. You can also pick up 10 dB of usable gain by setting the minimum SA attenuation to 0 dB instead of the default 10 dB. Spectrum analyzer allows you to see signals in the frequency domain, but for fast signals as LTE your instrument may be insufficient. You can see fast burst only if this is repeated many times, with the max peak function active, short span and low speed sweep. In this video, we show how to verify the gain performance of an RF amplifier using the SIGLENT SVA1015X spectrum and vector network analyzer. The video contains information on proper connections, attenuation, and basic use of SIGLENT spectrum analyzers and applies to the SSA3000X series as well.
