XSA805 Digital Spectrum Analyzer Spectrum Amplitude Frequency Analysis 9kHZ‑500MHZUS 100‑240V Item Type: Spectrum Analyzer Material: ABS Main Function: Display the spectrum, amplitude and frequency of the signal under test. It can be displayed in a panoramic view, or a bandwidth test can be selected. XSA805 Frequency Range 9kHZ-500.009MHZ Frequency resolution 1HZ Span 0HZ, 100HZ to the maximum frequency of the instrument Span uncertainty ± Span / (Sweep points -1) Carrier offset 10 kHz <-80 dBc/Hz 100kHz <-100 dBc/Hz 1MHz <-115 dBc/Hz Resolution bandwidth (-3 dB) 1 Hz-1 MHz (1-3-5-10 steps) Resolution bandwidth accuracy <5% typical Resolution filter shape factor (60 dB: 3 dB) <5 typical Video bandwidth (-3 dB) 10 Hz-1 MHz (1-3-5-10 steps) Amplitude measurement range DANL-+10 dBm, 100 kHz-10 MHz, preamplifier off DANL-+20 dBm, 10 MHz-1.5 GHz, preamplifier off Reference level -80dBm-+30dBm, step is 0.01dB Preamplifier 20 dB, nominal value, 100 kHz-1.5 GHz Input attenuator XSA805 0-40 dB in 1 dB steps Display average noise level (attenuator is 0dB, resolution bandwidth and video bandwidth are both 100 Hz, sampling detection, average number of traces ≥50, 20℃ to 30℃, input impedance is 50 Ω) Preamplifier off 9 kHz-1 MHz -95dBm (typical value), <-88dBm 1MHz-500MHz  -140dBm (typical value), <-130dBm Preamp on 100 kHz to 1 MHz -135 dBm (typical value), <-128 dBm 1MHz-500MHz  -160 dBm (typical value), <-150 dBm Frequency response (20℃-30℃, 30%-70% relative humidity, input attenuation 10 dB, relative to 50 MHz) Preamplifier off (fc≥9kHz)  ＜0.7 dB Preamplifier on (fc≥50 MHz)  ＜1.0 dB Absolute amplitude accuracy Uncertainty fc = 50 MHz, peak detector, preamplifier off, attenuator is 10 dB, input signal level = -10 dBm, 20℃-30℃
