Purpose and audience
The Thinkstar PLZ-PA35-4400-A01 is a portable spectrum analyser covering 35 MHz to 4.4 GHz with a tracking generator. It suits field engineers and hobbyists who need a handheld instrument for quick signal checks and basic spectrum display.
Frequency and interface limits
The analyser accepts input signals from 35 MHz to 4.4 GHz with a maximum safe level of +5 dBm and a typical noise floor of -70 dBm at 0.5 GHz. The tracking generator outputs across the same range at 0 dBm with 1 kHz step resolution, while frequency accuracy reaches ±0.1 kHz at 1 GHz after calibration.
Build and daily use
An aluminium alloy casing provides wear resistance for extended field life. A 3.5 inch touch screen replaces physical buttons for direct operation. Power is drawn from USB 2.0 or USB 3.0 at 5 V and 0.3 A, with USB 3.0 preferred, and an SMA connector handles RF connections.

Questions about this item
Which frequency range version should I choose for general-purpose RF testing?
This single model covers 35 MHz to 4.4 GHz, so one unit handles the entire span without needing multiple versions.
What does the 35 MHz to 4.4 GHz coverage mean when I connect it to a device under test?
You can measure signals from 35 MHz up to 4.4 GHz with 1 kHz step resolution and see input levels down to –80 dBm.
What does the USB 2.0 and 3.0 interface cap in practice for data transfer and power?
The USB port supplies 5 V at 0.3 A and carries control data; the SMA connector handles all RF signal input and output.
