The N9020B-508 covers 10 Hz to 8.4 GHz with DC coupling and 10 MHz to 8.4 GHz with AC coupling. The analyzer uses two bands: Band 0 from 10 Hz to 3.6 GHz and Band 1 from 3.5 to 8.4 GHz, both with LO multiplication factor of 1.
The N9020B-508 achieves -151 dBm DANL from 10 MHz to 2.1 GHz without preamplifier and -149 dBm from 3.6 to 8.4 GHz. With preamplifier enabled, DANL improves to -163 dBm from 10 MHz to 2.1 GHz and -162 dBm from 3.6 to 8.4 GHz, providing excellent sensitivity for weak signal detection.
At 10 dB input attenuation between 20 and 30 degrees C, the N9020B-508 delivers ±0.45 dB from 10 MHz to 3.6 GHz and ±1.5 dB from 3.5 to 8.4 GHz. With preamplifier on at 0 dB attenuation, accuracy is ±0.75 dB from 100 kHz to 3.6 GHz and ±2.0 dB from 3.5 to 8.4 GHz.
Standard configuration includes 25 MHz analysis bandwidth. Optional bandwidths include 40 MHz (Option B40), 85 MHz (Option B85), 125 MHz (Option B1A), and 160 MHz (Option B1X). The wider bandwidth options enable real-time spectrum analysis with Options RT1 or RT2 and support high-speed I/Q data streaming applications.
The N9020B-508 supports real-time analysis up to 160 MHz bandwidth with Options RT1 or RT2, which require Option B85, B1A, or B1X. RT1 provides basic detection with 11.42 ns minimum detectable signal duration and 17.3 microsecond minimum duration for 100% frequency mask triggering. RT2 offers optimum detection with 5.0 ns minimum signal duration and 3.57 microsecond minimum for 100% FMT probability.
With two -18 dBm tones at the input mixer, the N9020B-508 achieves -84 dBc distortion from 10 to 100 MHz (typical TOI +12 dBm to +17 dBm), -90 dBc from 100 to 400 MHz (typical +15 dBm to +20 dBm), -92 dBc from 400 MHz to 1.7 GHz (typical +16 dBm to +20 dBm), and -90 dBc from 3.6 to 8.4 GHz (typical +15 dBm to +18 dBm).
Yes, the N9020B-508 supports Noise Floor Extension with Option NF2, which provides more than 9 dB DANL improvement with 95% confidence across all bands and paths. With NF2 enabled, Band 0 achieves -162 dBm (preamp off) and -172 dBm (preamp on), while Band 1 achieves -160 dBm (preamp off) and -170 dBm (preamp on).
The N9020B-508 uses a Type-N female connector with 50 ohm nominal impedance for the RF input. This is standard for all RF and microwave frequency options (503, 508, 513, and 526). The analyzer also features front-panel USB ports, probe power connector, and optional external mixing capabilities for frequency extension.
