# Aim-TTi TG2511A 25MHz Function/Arbitrary/Pulse Generator # Aim-TTi TG2511A 25MHz Function/Arbitrary/Pulse Generator ## Key Features At A Glance - Sine and square output up to 50MHz (25MHz on the lower-frequency models) across the series - 14 digits or 1µHz frequency resolution from a 1ppm TCXO timebase - Arbitrary waveforms up to 128K points at 125MS/s with 14-bit vertical resolution - True pulse generator with independently variable delay and rise/fall times - Comprehensive AM, FM, PM, PWM, FSK, BPSK, Sum and PRBS internal/external modulation - USB and LXI-compliant LAN standard for automated systems; GPIB (IEEE-488) optional - 20mV to 20V pk-pk output from 50Ω over the full frequency range - Single- or dual-channel models; dual units add coupling, tracking and phase offset The TG5011A and TG2511A are DDS-based function, arbitrary and pulse generators, with the TG5012A and TG2512A providing two-channel versions of the same instruments. Built on a direct digital synthesis architecture with a TCXO timebase, the series combines standard function-generator waveforms, a true pulse generator and arbitrary waveform capability in a compact half-rack 2U casing with protective buffers and a carry handle. A function/arbitrary/pulse generator produces controllable, repeatable signals to stimulate a device under test. Standard waveforms include sine, square, ramp, pulse, sin(x)/x, noise, exponential, logarithmic and PRBS, and a PRBS (pseudo-random bit sequence) output can act as either a carrier or a modulator — a signal type used within secure communications systems. Phase-locking two generators provides outputs at the same frequency or harmonics with an adjustable phase difference, and modulating their amplitude and phase provides the capability to perform QAM and QPSK. ValueTronics stocks and holds its own inventory in a 20,000 square-foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois, giving customers a single accountable source for this equipment. ## Compare Other Models in This Series The TG2511A, TG5011A, TG2512A and TG5012A make up a single family of DDS-based function, arbitrary and pulse generators that share the same core architecture, control system and feature set. Four versions are offered: 25MHz and 50MHz frequency ranges, each available as a single-channel or two-channel instrument. The two-channel TG2512A and TG5012A are two-channel versions of the single-channel models with identical features, augmented by multi-channel capabilities including frequency and level coupling, full tracking and a defined phase offset. On the two-channel models both channels provide the full performance and specification and can be operated as entirely independent generators. Each model below links to its own dedicated product page with condition-matched pricing for the new configuration you select. Choose the model that matches your required frequency range and channel count, then select the available new option on that model's page. The TG5011A is the single-channel 50MHz model, providing sine and square output across the family's full 1µHz to 50MHz range with square-wave rise and fall times below 8ns. Frequency range is the primary differentiator: the TG5011A and TG5012A cover 1µHz to 50MHz, while the TG2511A and TG2512A cover 1µHz to 25MHz. The higher-frequency models also offer faster square-wave edges (below 8ns versus below 13ns), a higher PRBS bit rate (to 50Mbps versus 25Mbps), and a wider pulse repetition range, as detailed in the comparison table below. The second differentiator is channel count: the TG2512A and TG5012A add a second identical output with frequency, amplitude and offset coupling, tracking and an adjustable inter-channel phase offset, whereas the TG2511A and TG5011A are single-channel instruments. Ramp and triangle waveforms extend to 1MHz on the 50MHz models and 500kHz on the 25MHz models.
