• Tektronix 571 Curve Tracer
• Philips PM3632 Logic Analyzer
  The Philips PM3632 Logic Analyzer is a 32 channel logic analyzer capable of tracking 100 MHz state transitions at reduced channels. Alternatively up to 12.5 MHz can be used at the full 32 channels.
• Philips PM3632 Logic Analyzer (broken, spare parts)
  The Philips PM3632 Logic Analyzer this unit is broken and primarily intended for spare parts
• Philips PM5715 Pulse Generator
• PM6654 programmable timer / counter
  This programmable counter / timer from Philips is a very versatile unit capable of many computations including pulse width, rise and fall time and duty cycle across. The device has two inputs and is able to compute differences between the two including phase. Custom computations between the two inputs can be defined and enabled using the 9 digit keyboard. Several limitations apply to more complex computations such as those of phase and rise and fall time. These typically manifest in a mandatory dead time of several 10s to 100s of nanoseconds which severely reduces the maximum frequency (2 MHz for phase & 10 MHz for rise and fall).
• PM5771
  The Philips PM 5771 is a pulse generator operating from 1 hz to 100 Mhz with fine grained pulse shaping controls.
• HP 54501A
  The 54501A is a digital oscilloscope with 100Mhz bandwidth and 4 channels. The device is quite feature rich for its era have dedicated measurement functionality for frequency and amplitude analysis. Up to three measurements can be active at any given time. Other notable features include the ability to store four waveforms in nonvolatile memory, autoscaling and averaging using up to 2038 samples
• Hameg HM 1005
  The Hameg HM1005 is a dual channel analog oscilloscope with 50Mhz bandwidth. Notable features include a delay timebase and 10x horizontal zoom. Notably, the delay timebase offset is configured using a digital circuit with LED bubble display.
• HP 16500B
  A mainframe for HP series logic analyzers from the 1990s. Suitable for analyzing parallel data buses.
• PM3206
  The Philips PM3206 is a 15Mhz bandwidth dual trace oscilloscope using integrated circuits (ICs). The scope features an X * Y multiplication mode as well as 5x horizontal zoom. It is not to be confused with the Philips PM3206 oscilloscope released in 1964 that instead was entirely based on vacuum tubes.
• HP 1653B
  A 32 channel logic analyzer with 25Mhz state using the dreaded HP (not IBM compatible) floppy system to boot. Although utilities like lifutil exists by far the most complicated part of maintenance is the practice of restoring boot floppies and drives.
• PM3253
  A Philips PM3250 series oscilloscope with X*Y multiplication and analog storage features. These features are denoted by incrementing the part number by one and two respectively. This is why this model is known as the PM3253. Made in the early 1970's this was a very capable oscilloscope offering a 50Mhz input bandwidth and two individual time bases. As was typical for the era, these models are entirely build using discrete transistors each and every one on their own tiny standoff post.
• PM3250 X
  The Philips PM3250 X is a base model of the 1970's PM3250 series. This specific model has dedicated buttons for mains and video triggering which where features commonly used during television repair and maintenance. Like all PM3250 series the input bandwidth is 50Mhz and the device has two dedicated time bases. The internal construction is achieved using entirely discrete transistors each of them on a small plastic standoff.
• Type 453
• PM3410
• PM3370
