Aim-TTi TGR205x V2 Series: Application Note on RF Test Optimization

The new generation of TGR2051 and TGR2053 V2 RF signal generators from Aim-TTi redefines the standard for benchtop instruments and automated systems. Offering an unprecedented performance-to-price ratio, these devices are designed to excel in development, testing, and technical service environments.

1. Precision and Signal Stability

The V2 series introduces significant improvements in signal integrity. For applications requiring extreme precision, the instrument offers superior linearity and a drastic reduction in unwanted components.

• Amplitude Flatness: ±0.15 dB.
• Amplitude Accuracy: ±0.3 dB.
• Signal Quality: Optimization of harmonics, spurious emissions, and VSWR for reliable signal consistency across the entire frequency range.

2. Modulation Flexibility

The TGR205x V2 stands out for its ability to handle complex modulation scenarios, both analog and digital.

Analog Modulation

An integrated DDS generator allows for the creation of waveforms (Sine, Square, Ramp, Triangle) for AM, FM, or PM modulations.

• Internal Range: 1 mHz to 1 MHz.
• External Modulation: Ability to apply signals via the MOD input/output on the rear panel.

Advanced Digital Modulation

The instrument supports a wide range of protocols and filters, making it suitable for modern communication standards:

• Types: FSK, GFSK, MSK, GMSK, HMSK, 3FSK, 4FSK, PSK, ASK, and OOK.
• NRZ Patterns: Square waves and PRBS at 7, 9, 11, and 15 bits.
• Filtering: Gaussian, Raised Cosine, Root Raised Cosine, and Half Sine.

3. Advanced Features for Realistic Testing

Simulation of Dynamic Scenarios

One of the most powerful features of the V2 version is the ability to use Sweep and Modulation simultaneously. This combination allows for the evaluation of the device under test (DUT) behavior under variable and realistic RF conditions.

• EMC Applications: Essential for testing resistance to wideband interference and variable disturbances.
• R&D: Ideal for evaluating filters, antennas, and receivers in dynamic rather than static scenarios.

Custom Modulation Patterns

Users can define specific patterns of up to 16,384 states. These patterns can be:

• Created directly from the front panel.
• Imported via digital interfaces or USB Flash drive port.
• Executed in continuous or triggered mode (internal, external, manual, or remote).

4. Integration and Design

Despite its high performance, the TGR205x V2 maintains a compact and lightweight design.

Conclusion: Whether it involves basic research or rigorous compliance testing, the TGR205x V2 series offers the stability and versatility required for today's RF challenges, while maintaining the historic reliability of the Aim-TTi brand.
