When you're equipping a test bench, the little accessories can decide whether a measurement goes smoothly. Do you need a dedicated diode test fixture for vintage Tektronix gear, or a pair of general-purpose oscilloscope clip probes for everyday signals? This comparison puts the Tektronix Diode Test Fixture Adapter 013-072 next to the Peakelect 2-Pack Oscilloscope Clip Probes 200MHz to help you choose.
Quick verdict
If your projects center on vintage Tektronix gear and diode testing, the Tektronix 013-072 is the purpose-built adapter to consider. If you need a versatile pair of oscilloscope probes for frequent bench measurements, the Peakelect 2-pack is the practical way to go.

Where the Tektronix 013-072 wins
The Tektronix adapter is built around one specific job: plug-in diode testing. That focus is valuable when you're restoring vintage instruments or doing bench-side checks on gear that already uses the Tektronix-style connector layout. It's a fixture you reach for when you want a repeatable diode-test setup, not a flexible probe for signal tracing.
Where the Peakelect 2-Pack wins
The Peakelect kit is the more general-purpose option. The 200MHz rating and the ability to switch attenuation give you flexibility for everyday scope signals, and the kit comes with more than one probe so you can keep working when one is in use. It's the kind of set that earns a permanent spot on a busy workbench.
Product notes
Tektronix Diode Test Fixture Adapter 013-072 Electronic Test Accessory Vintage
This is a specialized fixture rather than a probe pair. The housing is black with beige/gray connector housings, and the terminal layout follows the Tektronix-style setup. It's labeled with E and C terminal markings, so it speaks directly to diode testing in vintage Tektronix setups. The obvious limitation is scope: if you need to make oscilloscope voltage measurements, this fixture won't do the job of a general-purpose probe. It also carries a higher price, so it makes the most sense when your bench is already built around Tektronix fixtures. For a restorer or a dedicated diode-testing bench, that focus is the reason to choose it.
Peakelect 2-Pack Oscilloscope Clip Probes 200MHz with Accessory Kit 1X 10X
These clip probes have a sliding attenuation switch, so you can move between 1X and 10X as your measurement needs change. The included accessory kit adds convenience, and the grounding crocodile clip gives you a stable ground path. The kit is well suited to common oscilloscope tasks. The main limitation is that they are not a diode test fixture and won't replace a vintage Tektronix adapter in that role. At $19.99, the set is the lower-cost way to add flexible scope connectivity to your bench, especially if you're just starting to build out equipment.
Final choice by use case
Choose the Tektronix Diode Test Fixture Adapter 013-072 if you're working on vintage Tektronix equipment or want a dedicated fixture for diode testing. Choose the Peakelect probe kit if you need general-purpose scope probes with switchable attenuation and a lower-priced bench entry point.
