content: Hello everyone! Here's something little bit different for sale: Agilent 66321B Mobile Communications DC sourceIn addition to having typical bench DC voltage source features, it can also emulate a battery (with a custom battery internal resistance setting) and sink DC current and measure it accurately. It can capture output voltage and current waveforms in 4,096 point buffer at up to 64 KSa/sec rate @ 16 bit resolution.Note that operating input voltage is 220-230V. There are few scratches in sides and in the rack mount bracket, but the front panel is practically flawless, no scratches. No cables are included, but I will include the rack mount bracket and 5-terminal block for no extra fee (see picture below).Calibration was done in 5/2012. Warranty void sticker looks broken, but this unit has not been opened by me (previously used by Nokia/Renesas/Broadcom R&D).Manufacturers description:The Keysight Mobile Communications DC Source 663xx series offers several features ideal for testing wireless and battery powered devices. Excellent voltage transient response ensures maximum test-system throughput by minimizing device shutdowns due to significant voltage drops in the test wiring. Built-in advanced measurement system to accurately measure battery current drains when the device operates in different modes and a Keysight-developed feature that enables cellular telephone manufacturers to detect permanently and intermittently open-sense wire connections.The Keysight 66321B mobile communications dc source provides fast transient response, exceptional sourcing, output resistance programming, and precision measurement. This product is specially designed for testing next generation digital wireless communications products. The 66321B mobile communications dc source offers a new capability that simulates the internal resistance of a battery or battery pack. Additionally, these high performance models offer improved transient response and stable output operation with either short or long load leads.Output RatingsVoltage: 0 to 15 VCurrent: 0 to 3 APeak Current for up to 7 ms: 5 AProgramming accuracy at 25°C ±5°C (% of setting plus fixed)Voltage: 10 mV+ Current: 1.33 mADC Readback AccuracyVoltage: 0.03% + 5 mVCurrent (-3 A to + 5 A): 0.2% + 0.5 mACurrent (-1 A to + 1 A): 0.1% + 0.2mACurrent (-20 mA to + 20 mA): 0.1% + 2.5 µATransient Response40 mV drop, <20 µs transient response timeMore detailed specifications:http://www.keysight.com/upload/cmc_upload/All/66300series_datasheet_Jan07.pdfUsers guide:http://literature.cdn.keysight.com/litweb/pdf/5964-8184.pdfPictures:Measurements:Test setup10V via 22.2 ohm resistor ( true value 450.45 mA, 0.8% deviation )5V via 10K resistor ( true value 0.5 mA, 0.2% deviation )5V via 1 Mohm resistor ( 5 microamps, no deviation could be measured )High resolution images can be found here:Agilent/Keysight stilll sells these for around 2400 euros. My asking price is 690 euros (VAT 24%). Postage fees from Finland are excluded (Will ship worldvide. Around 50-70 euros to Europe for 12kg package, please ask for exact value). VAT can be lifted for VAT-registered companies in EU.I will give return policy of 14 days (buyer pays for return postal fees).I am also willing to do more detailed, custom tests and take more pictures as per your instructions.UPDATE 26.9.2015: Moved this item to eBay.http://www.ebay.co.uk/itm/-/271997683143?
