UHF-MF 멀티 주파수

The UHF-MF Multi-frequency option adds another 6 internal oscillators to the instrument and allows a free choice of frequency for every of the 8 demodulators. This extends the capability of the UHF Instrument tremendously by offering a wide range of additional configurations for measurement and signal generation.

UHF-RUB 루비듐 원자 시계

The UHF-RUB upgrade option provides an atomic frequency standard to the UHFLI instrument. Experiments in need of a high frequency accuracy and stable operation over long periods of time even in adverse conditions, e.g. laboratories with limited climate-control, can rely on the Rubidium based atomic clock. Moreover, calibration demands are also further reduced as there is essentially no clock aging. The UHF-RUB is a hardware option that cannot be upgraded later in the field.

UHF-CNT 펄스 카운터

The UHF-CNT Pulse Counter features analysis of up to 4 pulse trains in parallel, enabling event based measurements, e.g. photon detection using photo-multiplier tubes. There are five distinct modes of operation and each channel offers an adjustable discriminator. The maximum count rate is 225 MHz. Measurement results from the pulse counters can be conveniently analyzed with the LabOne® toolset, which features time domain and histogram display.

UHF AWG 하이라이트

The UHF AWG can reproduce any waveform from a user-programmable 128 MSa memory on its two 600 MHz output channels. The high-level compiler integrated into the LabOne user interface centralizes the tools for waveform creation and editing, sequencing, and instrument configuration, ensuring an efficient workflow towards the desired output signal. Find out more about the AWG's programming concept here.

Moreover, the UHF AWG is equipped with two 600 MHz signal inputs and a measurement toolset offering a variety of synchronous and asynchronous detection methods. The cross-trigger engine enables bidirectional triggering between the AWG and the internal detection units, representing a superior replacement of inter-device triggering used in traditional measurement setups. It eliminates complicated synchronization methods between separate instruments for signal detection and signal generation. Instead, the measurement procedure is controlled from a single AWG program as illustrated with the example shown below.

Analog and digital AWG signals generated by the program above. Data acquisition (here: homodyne detection) is performed synchronously with signal generation.

The platform-independent LabOne user interface provides an extensive measurement and analysis toolset:

  • With the parametric Sweeper, dependencies on AWG parameters such as waveform amplitude, delays, or carrier frequency and phase are easily measured.
  • Continuously streamed measurement data are visualized with the Plotter tool and offer a close monitoring of the effect of the AWG signal.
  • Triggered recording is available using either the built-in Scope or the Software Trigger tool to accommodate for the often shot-like character of AWG measurements.
  • The LabOne programming interfaces (API) for Python, LabVIEW, MATLAB, and C allow for quick integration into existing control software.

UHF AWG 상세 설명

파형 생성 및 변조

The UHF AWG offers two distinct output modes:

  • In direct output mode, the waveforms are routed directly to the DC-coupled signal outputs. The 128 MSa waveform memory and 14-bit, 1.8 GSa/s D/A conversion enable generation of high-resolution pulse shapes to reproduce a wide range of device testing conditions or to compensate for distortions occurring in the signal path.
  • In amplitude modulation mode, each AWG channel shapes a sinusoidal signal generated by an internal oscillator. It optimizes the generation of phase-coherent pulse patterns using the sequencer and generic pulse envelopes, without which the entire waveform needed to be uploaded. This saves time and increases throughput. Variation of carrier parameters helps in cases where frequent tuning of phase or frequency is required. In applications such as NMR spectroscopy that require long patterns at the full 600 MHz bandwidth, the user can reduce waveform size by specifying envelopes with a lower sampling rate than the final signal.

Find out more here about the AWG's capabilities for modulation and triggering. The UHF-MF Multi-frequency option further enhances the modulation features. It enables fast switching between up to 8 frequencies in a pulse sequence, and precise inter-channel phase control ideal for external I/Q mixing.

The UHF AWG's internal oscillators are references for both signal generation and signal detection, which enables measurement of the phase in applications such as pulsed radar. Two digital marker signals per channel can be generated with the same time resolution as the analog signal both in direct output mode and amplitude modulation mode.

The UHF AWG can be combined with a range of detection units in the same instrument:

  • Multiple Demodulators enable phase-sensitive detection with a best-in-class 5 MHz measurement bandwidth for pulsed RF measurements.
  • The Pulse Counter option is for convenient processing of PMT or similar pulse-like signals with rates up to 225 MHz.
  • The Scope/Digitizer enable direct visualization of system response to a waveform stimulus.
  • The Spectrum Analyzer provides the high frequency resolution required e.g. in NMR spectroscopy.
  • The Boxcar averager offers a precise analysis of fast periodic signals with low duty cycles.


시퀀스 분기와 피드 포워드

Using its branching capabilities, the UHF AWG can select the next waveform based on external conditions such as the state of the 32-bit digital input, or internal conditions such as the value of a demodulated signal quadrature. The flow diagram below illustrates the flexibility in defining branching conditions for different applications. Achieving sub-microsecond feed-forward times is a matter of a few sequencer commands and there's no need to manage low-level digital signal processing.

This example shows the signal path for a fast feedback protocol. A feedback latency below 1 µs is reached for a protocol including demodulation and conditional branching. Direct AWG trigger delay is less than 150 ns.
