  • HP 6060B System DC Electronic Load: Adjustment

    HP 6060B System DC Electronic Load: Adjustment

    Currently, the unit’s setpoint accuracy isn’t all that great (readback resolution is limited as well, but shows the offset): Regardless of the range it has an offset of about +20 mA. Sure, for a unit capable of 60 A that seems reasonable, and well within its specs of ±0.1% ±75 mA. But since I’ll use…

    HP 6060B System DC Electronic Load: Teardown, Service

    I recently got my hands on a HP 6060B System DC Electronic Load (later also sold as Agilent 6060B). My unit has option 020 installed: Comically large binding posts also on the front panel. This option certainly is not unheard of, but not too common either. Retrofitting is possible, but can be quite some work.…

  • Breakout box for Agilent 6611B AC Power Source

    Breakout box for Agilent 6611B AC Power Source

    I got my Agilent 6611B AC power source/analyzer a few weeks back, but hadn’t used it as much as I wanted. The reason was simple: The connections are made with rear mounted screw terminals – hence it was just a bit inconvenient to interface with products and circuits. The solution was really simple: A Hammond…

  • A Nice Case for Projects

    A Nice Case for Projects

    For projects like the programmable resistor I was looking for a case, preferably made of aluminum and 19″ compatible. In order to save some space on the desk I hoped to find one with a width of 42HP (i. e. half width). What I found was a beautiful case made by ELMA (2 RU, 42HP),…

  • SCPI Capable Thermometer

    SCPI Capable Thermometer

    For a long time I wanted to build an SCPI capable thermometer to keep track of the ambient temperature in my small lab. The list of requirements was fairly short: Design After researching temperature sensors I chose a Texas Instruments TMP117M temperature sensor with quite impressive specs. With an accuracy of ±0.1°C (max.) between 25°C…

  • HP Instrument feet

    HP Instrument feet

    Many older HP/Agilent instrument share a similar feet design. There are at least two different types though: One with a metal part to prop up the instrument and one without it that can be used on all four corners. The feet can be detached from the instrument, e. g. for use in 19″ racks. This…
