The May 2024 Photo of the Month is a really interesting one because of the number of Tektronix instruments on the bench. Many have large number labels which might indicate Pool instruments and some have the plastic covers which typically were manufacturing samples. The unidentified employee is working on a 6R1 digital readout plug-in board and several plug-in boards are extended from the side of the 6R1.

In the photos is a 575 Curve Tracer on a 500 series Scope-Mobile which holds a Type H Wide-band Calibrated Preamp and a Type Z Calibrated Differential Comparator plug-in. The 567 Sampling Oscilloscope has the typical 3S76 Sampling Dual Trace, 3T77 Sampling Sweep, and the 6R1 Digital Readout plug-ins. On the bench is a Type 545A 30 MHz Oscilloscope, a Type 105 Square Wave Generator, and an obscured test instrument. On the shelf is a Type TU75B Power Test Set, a Type 77TU Line Voltage Control Unit, a Type 190B Constant Amplitude Signal Generator, and a Type 130 L-C Meter. This is quite the engineering bench and we'd love to identify the employee.
