HP Agilent 33120A AWG Opt 001

There are some units on eBay, but the sellers mostly don’t know and describe them as having the “Opt 001” inside, a.k.a. 33120-80001, a.k.a. 33120-66503.

The Option 001 phase lock/TCXO timebase gives you the ability to generate synchronized phase-offset signals. An external clock input/output lets you synchronize with up to three other 33120As or with an external 10-MHz clock.

Agilent E3644A Labornetzteil

Letztens habe ich in der Bucht ein Labornetzteil erstanden, den Agilent (jetzt Keysight, vorher HP) E3644A. Es ist ein 80W, 8V/8A oder 20V/4A. Die Bereiche sind fliessend, es kann einfach über 8V nur noch 4A liefern. Dabei ist es ein analog ausgeführtes, digital gesteuertes Netzteil, mit GPIB, RS-232, remote-sense usw.

Max freq of test equipment

Many measuring devices have a maximum frequency up to which they work correctly, as stated by the manufacturer. Above that frequency they don’t just stop working, rather they still have a range above where they still may work correctly, just aren’t as sensitive. Many oscilloscopes, for example, can work up to twice their bandwidth, but the measured amplitudes are not more than some random numbers. You can still see the waveform, but not do any meaningful measurements.
