I discover the HP 5370B Universal Time Interval Counter. A transistor in the power supply was over 80 °C. This temperature is a bit too high. It is a Motorola with the HP part number 1853-0411. Is there an alternative to this transistor? I haven't found anything on the internet.

Today on the bench, an HP 54100D Digitizing Oscilloscope with 1Ghz bandwidth and active probes. An interesting device with 68k CPU and a very nice display. Using the menus is a bit difficult.

HP 9000 310 Suddenly the HP hard disk in the HP 9153C repaired itself and an initialization was started. I am trying to install the HP Basic 5.1 on the hard drive.

HP 8757C scalar network analyzer, HP 8350B sweep oscillator and HP 7470A Plotter in combination to measure an LP filter. Plotters are simply beautiful! 😁

An attempt to read the RTTY messages decoded by the R&S GA 082 with the HP 4951C protocol analyzer. The RTTY signal is from the German weather service.

The HP 5060-0329 encoder is more complicated than I thought. Does anyone have schematics for this? #hp6034a #hppowersupply

I tested it with a normal LED because of its simplicity. It did not work.

It looks very exciting under the microscope. The tungsten bulb is defective. The diodes are really very small.
