Choosing the right tool for RF network cable and telecom test work comes down to a basic question: do you need to create a signal, or do you need to see what a signal is doing? The EICO Model 324 is a vintage signal generator that produces radio-frequency test signals. The Tektronix 2712 is a spectrum analyzer that displays and measures signals across a wide frequency span. They serve very different parts of the bench.
Quick Verdict
If you mainly need a dependable RF signal source and want to keep the investment small, the EICO Model 324 at USD 99.99 gets the job done. If you need to analyze signal behavior, run frequency sweeps, and connect to automated test gear, the Tektronix 2712 at USD 599.49 is the instrument that can handle it. The two are USD 499.50 apart, and that gap buys a lot of measurement power.

Where Each Product Wins
- EICO Model 324: Choose it when your work is mostly generating RF signals and you want a simpler, lower-investment instrument. It is made in the United States and has a gray vintage look.
- Tektronix 2712: Choose it when you need to measure signal behavior and drive automated instrumentation. The 9kHz to 1.8GHz coverage and IEEE-488 interface give it a clear measurement advantage.
Product Notes
EICO Model 324 Signal Generator Vintage RF Radio Test Equipment FULLY WORKING
The EICO Model 324 is a fully working vintage signal generator with a gray case. It is made in the United States and designed for radio-frequency testing, which makes it a practical source when you need to inject a signal into a circuit or align an older radio. Choose it for the lower end of the price spread and simple role. The downside: it is a signal generator only. It can produce RF test signals but cannot display a spectrum or analyze signal content. For a bench focused on straightforward RF signal generation, that limitation is easy to accept. The EICO's appeal is the combination of a working vintage tool, a modest price, and a clear single purpose.
Tektronix 2712 Spectrum Analyzer 9kHz-1.8GHz 50Ω RF Test Equipment USA W/ Manual
The Tektronix 2712 is a used, United States-made spectrum analyzer covering 9kHz to 1.8GHz with a 50Ω RF input. It includes the manual, and its controls extend to a CRT display with on-screen menus, a numeric keypad, frequency and span controls, resolution bandwidth and sweep controls, display storage A/B/C/D keys, a tracking generator output, an external trigger, and an IEEE-488 (GPIB) interface. If you need to see what a signal is doing across a wide frequency span, this is the instrument for RF network cable and telecom test work. The trade-off is complexity: the menu-driven CRT interface has more steps than a simple generator, and the price is much higher. But when the job demands measurement, automated control, and detailed signal analysis, the Tektronix 2712 provides the capability.
Final Choice by Use Case
- RF signal injection and vintage radio servicing: The EICO Model 324. It is a signal generator at the lower end of the price spread and keeps the bench uncomplicated.
- Spectrum analysis and automated telecom testing: The Tektronix 2712. Its range and GPIB connection cover RF network cable and telecom test needs that a signal generator alone cannot.
