Description
The signals that cause trouble are often the ones that come and go. The Tektronix RSA503A spectrum analyzer is a small USB real-time analyzer that tunes from 9 kHz to 3 GHz and watches a 40 MHz slice at a time. A spectrogram then shows when each burst appeared. Lost in HCM lists it for rental and sale, with service on request.
Catching bursts and spurs
The SignalVu-PC software turns the stream into spectrum and spectrogram views. These views show which channels are busy, where spurious components sit and how RF activity changes over time. For example, a product team can see whether a stray emission appears only during a radio transmission. Installed options then decide how far the advanced measurements go.
What the 40 MHz window means
The 40 MHz figure is the instantaneous real-time acquisition bandwidth, not the tuning range. The analyzer still tunes anywhere between 9 kHz and 3 GHz. However, it analyzes only one 40 MHz window at a given moment. So plan wide surveys as a series of steps.
Choosing the computer
This analyzer has no screen or controls of its own. Instead, the connected computer supplies both, over USB 3.0. Because the listing does not assume a computer comes with it, budget for one. Also check the current SignalVu-PC requirements first, and confirm any modulation, recording or measurement licenses you want.
Hook-up order
- First, place a suitable attenuator or DC block ahead of the RF input when the source needs one.
- Then connect the USB 3.0 cable to the host computer.
- Attach an antenna for receive-only measurements.
- Finally, keep high-power transmitters away from the input unless you add proper protection.
Also read the input power, DC limits and connector ratings in the instrument manual.
Rent a Tektronix RSA503A spectrum analyzer or buy one
The unit is a portable, battery-powered field analyzer. Besides, a tracking generator is optional, so confirm the installed configuration. A short troubleshooting job suits a rental, but a team that scans RF every week may prefer to own one. Please request a quote from Lost in HCM with your frequency range, signal levels, options and accessories. The category page lists more spectrum and signal analyzers from the same partner. If you are unsure about fit, contact SMK Vietnam and ask. The Tektronix website hosts the RSA500 datasheet.
Tektronix RSA503A spectrum analyzer questions
Does 40 MHz limit the frequency range?
No. The analyzer tunes from 9 kHz to 3 GHz, and the 40 MHz figure describes only the real-time window at one moment.
Does the listing include a computer?
No. Choose a computer that meets the SignalVu-PC requirements, because the listing does not assume one.
Is a tracking generator fitted?
It is optional. Confirm the installed configuration of the unit you rent or buy.
