Description
A local oscillator or synthesizer output can sit well above what a basic counter reads, yet it still needs checking. The Tektronix FCA3103 frequency counter reads up to 3 GHz and resolves single-shot time intervals down to 50 ps. Lost in HCM lists it for rental and sale, with service available on request.
Reaching 3 GHz
The frequency ceiling is the main difference from the 300 MHz counter in the same series. At this range, the connection matters as much as the instrument. So follow the manual to find the input for your frequency. Microwave measurements use the high-frequency input where one is fitted.
The numbers that matter
The counter resolves 12 digits per second in frequency and 0.001 degree in phase. It also has USB and GPIB for remote control. Meanwhile, TrendPlot, histogram and statistics views show how repeated readings behave. An optional oven timebase is available, so specify the stability and calibration you require.
Jobs for the Tektronix FCA3103 frequency counter
- Local oscillator and synthesizer checks, because their outputs reach the gigahertz range.
- Wireless module bring-up, while a second signal goes to input B for comparison.
- Reference and derived clock comparison, such as a master clock against its divided output.
- Long drift logs, since USB or GPIB lets a script store the readings.
Keep the signal path short
At 3 GHz, cables and connectors can weaken a signal, so keep the run short and use rated parts. Also confirm the voltage limits, termination and grounding before you connect. Above all, never feed mains power into a counter input.
Borrow it or own it
Rent the Tektronix FCA3103 frequency counter for a radio-frequency bring-up or an audit of a timing chain. Buy it instead when gigahertz checks happen every week. Because condition and availability vary, Lost in HCM confirms them for each quote.

FCA3103 questions
How does the FCA3103 differ from the 300 MHz model?
Both share 50 ps single-shot resolution and USB and GPIB interfaces. The FCA3103 reaches 3 GHz, while the FCA3100 stops at 300 MHz.
Can I log results to a computer?
Yes. USB and GPIB are both available, so scripts can collect the readings.
What should my quote request include?
Give your frequency range, signal levels, options and accessories, plus the delivery site. Lost in HCM confirms price, condition and availability individually.
