安捷倫 34401A 6位半桌上型數位電表
這一台我想應該不用多說吧, 它可能是全世界桌上型數位電表最有名的一台
在1992由HP開發生產, 雖然歷經了不同的公司改組 HP -> Agilent -> Keysight
全世界賣了幾十年, 幾乎無需改變設計!
它的設計及穩定性, 受到了許多工程師的喜愛, 在2016/12宣佈停產時, 許多人感到遺憾(至少我)
速度快又精準, 就算長年未校正, 仍保持相當的精度正確(不像後期設計需要常靠軟體校正)
The 34401A multimeter gives you the performance you need for fast, accurate bench and system testing. The 34401A provides a combination of resolution, accuracy and speed that rivals DMMs costing many times more. With 6 1/2 digits of resolution, 0.0015% basic 24-hr dcV accuracy and 1,000 readings/s direct to GPIB assure you of results that are accurate, fast, and repeatable.
- 1000 readings/sec. direct to GPIB
- Continuity and Diode Test functions
- Null feature allows you to remove lead resistance and other fixed offsets in your measurements
- Min / Max / Avg readouts
- Direct dB and dBm measurements
- Data Hold capability
- Store up to 512 readings in internal memory
- Voltmeter Complete and External Trigger signals provided so you can synchronise to other instruments
- TTL output indicates Pass/Fail
- TTL output indicates Pass/Fail

即將停產的是德科科技——原惠普(Hewlett-Packard；HP)——34401A數位萬用表。這款產品自推出後歷經該公司24年的「改朝換代」，預計將在今年底停產——HP量測事業群後來獨立成為安捷倫科技(Agilent Technologies)，其後又更名為是德科技。
