# Agilent 8514B S-Parameter Test Set, 0.045 GHz to 20 GHz, 3.5 mm (Pre-Owned) # Agilent 8514B S-Parameter Test Set, 0.045 GHz to 20 GHz, 3.5 mm (Pre-Owned) ## Key Features At A Glance - Frequency coverage from 45 MHz to 20 GHz for broadband RF and microwave network characterization - 3.5 mm male test port connectors at port 1 and port 2 with 50 ohm nominal impedance - Built-in step attenuator with 0 to 90 dB range in 10 dB steps for incident signal control - DC bias capability supports up to 500 mA and 40 Vdc maximum through the test ports - Receiver dynamic range up to 106 dB in the 2 to 8 GHz band for demanding transmission measurements - Residual directivity to 48 dB and crosstalk to 115 dB after calibration and error correction - Rear-panel 3.5 mm female RF input with +16 dBm maximum input power rating The Agilent 8514B is an S-parameter test set designed for vector network analyzer systems operating from 45 MHz to 20 GHz. It provides the signal separation, switching, and reference sampling hardware required to perform full two-port S-parameter measurements, with 3.5 mm male connectors at both test ports and a 50 ohm nominal port impedance. The 8514B is built around two test ports configured for transmission and reflection measurements across its full frequency range. Each test port carries a nominal operating power level of 2 to -6 dBm depending on band, and the test ports support DC bias up to 500 mA and 40 Vdc maximum for measurements that require an applied bias on the device under test. The rear-panel RF input connector is a 3.5 mm female with a maximum input power rating of +16 dBm. ## Brand Heritage The 8514B originated within Hewlett-Packard's test and measurement business. HP spun out its test and measurement instruments as Agilent Technologies in 1999, and that electronic measurement business was subsequently transferred to Keysight Technologies in 2014. Instruments carrying the original HP brand, the Agilent brand shown on this datasheet, and current Keysight branding share the same engineering lineage for this product family. ## Product Core & Specifications Specification Value General Frequency Range 0.045 to 20 GHz Test Ports (port 1 or 2) Nominal Operating Power Level 2 to -6 dBm Connector Type 3.5 mm, male Impedance, DC Bias 50 ohm nominal, 500 mA, 40 Vdc maximum Attenuation Range (incident signal) Range 0 to 90 dB, in 10 dB steps RF Input Connector (rear panel) Maximum Input Power +16 dBm Connector Type 3.5 mm, female Dynamic Range (for transmission measurements) Frequency Range (GHz) .045 to 2 / 2 to 8 / 8 to 20 Maximum Power Measured at Port 2 (dBm) +20 / +11 / +10 Reference Power at Port 1, nominal (dBm) +2 / -2 / -6 Minimum Power Measured at Port 2 (dBm) \-66 / -95 / -95 Receiver Dynamic Range (dB) 86 / 106 / 105 System Dynamic Range (dB) 68 / 93 / 89 Measurement Port Characteristics — Residual (dB) Frequency Range (GHz) .045 to 2 / 2 to 8 / 8 to 20 Directivity 48 / 44 / 44 Source Match 40 / 33 / 31 Load Match 48 / 44 / 44 Reflection Tracking ±0.003 / ±0.003 / ±0.006 Transmission Tracking ±0.017 / ±0.044 / ±0.084 Crosstalk 89 / 115 / 110 Raw (typical) (dB) (before calibration/error correction) Directivity 23 / 23 / 14 Source Match 17 / 15 / 11 Load Match 17 / 15 / 11 **Important:** Maximum input power at the rear-panel RF input connector: +16 dBm.
