UTS7000A-P13: 13.6 GHz Preamplifier

Overview

The UTS7000A-P13 preamplifier option adds an internal low-noise preamplifier covering 100 kHz to 13.6 GHz, lowering the analyzer's effective noise floor by approximately 15 dB across key measurement bands. For an RF engineer, this is the difference between seeing a signal and missing it entirely. Weak spurious emissions at -150 dBm, low-level harmonics from a power amplifier under development, or a faint conducted emission riding just above the noise floor—all of these become clearly visible measurements rather than ambiguous bumps in the noise. The preamplifier is engaged with a single front-panel button press and the analyzer automatically compensates gain and reference level, so there's no manual correction or recalibration required.

⚠ Factory-Installed Option: The preamplifier is a hardware option that must be ordered with the analyzer at time of purchase. It cannot be added in the field after delivery. Specify UTS7000A-P13 when placing your order.

What the Preamplifier Actually Does for You

Improves Sensitivity Where It Matters: With the preamplifier engaged, the UTS7013A/UTS7026A models achieve typical DANL of -162 to -167 dBm/Hz across the 1 MHz to 13.6 GHz range. Without it, you're working at -138 to -153 dBm/Hz at the upper end of the band. That 15+ dB improvement is the practical difference between detecting a spurious emission at -145 dBm (clearly visible with preamp) versus staring at noise (invisible without it).

EMC Pre-Compliance Testing: CISPR radiated emissions testing requires measuring signals down to regulatory limits that often approach -80 to -100 dBm at the antenna connector after cable and antenna correction factors are applied. Without a preamplifier, your measurement uncertainty increases dramatically as signal levels approach the analyzer's native noise floor. The P13 preamplifier provides comfortable measurement margin, reducing uncertainty and giving you confidence that a marginal pass really is a pass—before you spend $15,000+ at an accredited test lab.

Receiver Sensitivity Measurements: Characterizing the minimum detectable signal of a receiver front-end requires the test equipment noise floor to be well below the device under test. The P13 preamplifier ensures the analyzer doesn't become the limiting factor in your measurement chain, enabling accurate sensitivity measurements of LNAs, receiver front-ends, and antenna subsystems through 13.6 GHz.

Low-Level Spurious and Harmonic Hunting: When your PA design needs to meet -60 dBc spurious specifications, you need an analyzer that can actually see signals 60 dB below your carrier with margin. The preamplifier extends your effective dynamic range for low-level signal detection, making it possible to find and characterize spurious products that would otherwise be buried in the analyzer noise.

Frequently Asked Questions

Can I add the preamplifier later if I don't order it now?

No. The preamplifier is an internal hardware module installed during manufacturing. It cannot be retrofitted in the field. If there is any possibility you'll need improved sensitivity for EMC testing, weak signal detection, or low-level spurious measurements, order the preamplifier option with your analyzer. The cost of the preamplifier option at time of purchase is significantly less than replacing the instrument later.

Does the preamplifier degrade dynamic range or large-signal handling?

When the preamplifier is engaged, the input compression point drops from approximately +6 dBm to -15 dBm (at the mixer). This means you should not use the preamplifier when measuring strong signals. The preamplifier is designed for weak signal work—simply toggle it off when measuring high-level signals. The analyzer's input attenuator and auto-ranging functions help protect against overload, but good measurement practice is to disable the preamp for any signal above approximately -30 dBm at the input.

Which preamplifier should I choose—P13, P26, P32, or P40?

Choose the preamplifier that matches your analyzer's frequency range. The P13 covers 100 kHz to 13.6 GHz and works with all models, but only provides preamplification through 13.6 GHz. If you have a UTS7026A and need enhanced sensitivity above 13.6 GHz, choose the P26. Higher-frequency preamplifiers (P26/P32/P40) also cover the lower frequencies, so there's no need to stack options—one preamplifier covers your full range.

Do I need a preamplifier for EMI pre-compliance testing?

For conducted emissions testing (150 kHz – 30 MHz), the analyzer's native -145 to -151 dBm DANL is usually sufficient because LISN losses are modest. For radiated emissions testing (30 MHz – several GHz), the preamplifier is strongly recommended. After accounting for antenna factors, cable losses, and distance correction, received signal levels can be quite low—especially at higher frequencies where regulatory limits tighten and path losses increase.

See signals you're currently missing—the UTS7000A-P13 preamplifier extends your measurement reach where it matters most.
