Currently, the unit鈥檚 setpoint accuracy isn鈥檛 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 卤0.1% 卤75 mA. But since I鈥檒l use it in the low range (6A) most of the time and likely often even well below 1A that doesn鈥檛 seem too great, does it? ...
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. Huge binding post also on the front panel thanks to option 020 ...
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 also means they got thrown away too often, so that many used instruments come without them. For some time they were available on ebay at a reasonable price. ...
The HP 5328 series counters are a range of 0 to 100 MHz Universal counter from the 70鈥檚. While fairly similar on the outside, internally the updated B model differs from the A model significantly. The HP 5328B鈥檚 build quality impresses still today - even for the front panel they didn鈥檛 use plastic back then. Its specs however don鈥檛. The direct count measurement provides a resolution of up to 8 digits/s, far less than modern but much more expensive reciprocal counters (with an interpolator) achieve. In my configuration the counter features an 8 digit LED display. In contrast to most newer counters the HP 5328B has dedicated marker outputs (trigger outputs) for each channel on the front panel. ...
