It is suitable for technicians and engineers working with wireless systems, transmitters and receivers, offering practical mobility and straightforward operation for inspecting signal spectra.

## Long description

The extra digital TV991211 is a portable spectrum analyzer and handheld RF measurement instrument designed for field and laboratory use. It provides frequency analysis, signal level measurement and basic generator functions in a compact, battery-powered unit suitable for troubleshooting, signal monitoring and verification of wireless systems, transmitters and receivers.
Advantages
The TV991211 combines a 2.8" 320×240 resistive touchscreen with jog-switch control and USB serial connectivity, plus an internal linear power supply to reduce switching noise. It offers both low and high input/output modes, selectable resolution bandwidths, and optional features such as an internal reference generator and external attenuator. The unit supports quick scans with automatic optimization of scan points, multiple measurement resolutions and the ability to demodulate audio after a minor hardware modification.
Suitable for
Field testing and maintenance of wireless systems
Laboratory signal analysis and troubleshooting
Verification of transmitters, receivers and antenna systems
Education and training in RF measurement techniques
Key specifications
Display: 2.8" resistive touchscreen, 320 × 240 pixels, 16-bit RGB
Low input mode: 100 kHz–350 MHz (some limits to 10 kHz), 50 Ω with ≥10 dB attenuation, input level max +10 dBm, IIP3 +15 dBm, 1 dB comp. point −1 dBm, noise floor −102 dBm (30 kHz RBW)
High input mode: 240 MHz–960 MHz, frequency-dependent impedance, input level max +10 dBm, IIP3 −5 dBm, 1 dB comp. point −6 dBm, noise floor −115 dBm (30 kHz RBW)
Output (low): Sine 100 kHz–350 MHz, harmonics \< −40 dB, level −76 dBm to −6 dBm in 1 dB steps, AM/narrow FM/wide FM optional
Output (high): Square 240 MHz–960 MHz, level approx. −38 dBm to +9 dBm, narrow/wide FM optional
Resolution filters: manually selectable 3, 10, 30, 100, 300, 600 kHz; automatic choice among 57 filters; on-screen points 51/101/145/290
Frequency resolution: 156 Hz (below threshold) or 312 Hz (above) depending on band; frequency accuracy equals selected RBW
Scanning: \>1000 points/s with largest RBW; spur suppression option available
Reference generator: optional square output at selected MHz frequencies (1, 2, 4, 10, 15, 30 MHz)
Power: rechargeable battery, charge ≤1 hour from 500 mA USB, runtime ≥2 hours
Interfaces: USB serial port; optional TTL USART on internal PCB (software not yet implemented)
Warranty: 24 months
How to use
Power the unit from its internal battery or a USB source and use the resistive touchscreen or jog switch to select mode, frequency range and resolution bandwidth. Choose low or high input mode depending on the measured frequency, and set input attenuation manually or to automatic (0–31 dB in 1 dB steps) to protect the front end and optimize measurements. Use the generator outputs for signal injection or alignment tasks, selecting modulation or sweep functions if needed. Connect via the USB serial port for remote control or data transfer; note that the optional TTL USART requires software support not yet implemented.
Usage recommendations
For accurate measurements, keep input power below −25 dBm when possible, use appropriate attenuation settings, and select an RBW that balances sensitivity and scan speed. Avoid strong out-of-band signals in high input mode to reduce distortion, and perform a power level calibration to achieve the stated ±1 dB accuracy.
