  • Plus 4x optional outputs
  • User friendly front panel operation, selectable for eight languages
  • Use of both GLONASS and GPS gives better signal coverage (GPS-12RG)

Frequency Distribution Amplifiers

The Pendulum Frequency Distribution Amplifiers, FDA-301 and DA-36, offer an economical solution to low-jitter and long-range distribution of Frequency Reference and/or Time Synchronization Signals.

The versatile and modular FDA-301 can distribute sine reference frequencies and time synchronization signals (1-pps and unmodulated IRIG) from a central source to up to 18 remote sites (point-to-multipoint). Additionally, it can distribute serial Time-of-Day messages (NMEA or user defined code) and telecom sync signals (E1/T1 clock/data).


Key Specifications

  • Distribute reference frequency (10 MHz default)
  • Distribute 1-pps, IRIG (DCLS) and serial T.o.D.
  • Distribute E1/T1 sync signals (clock/data)
  • Fiber and coax distribution
  • Modular outputs; up to 18 fiber / 12 coax
  • Input signal redundancy with auto-change-over

High Voltage Linear Amplifiers

Pendulum Instruments High Voltage Linear Amplifiers are general purpose broadband linear amplifiers having a fixed or variable amplification, and capable of bipolar or unipolar output. The amplifiers outputs are linear from DC up to Megahertz range, and exist in Single-Channel and Dual-Channel versions.

Pendulum Instruments High Voltage Linear Amplifiers are valuable tools, for research institutes, R&D labs and component manufacturing industries, in a wide range of applications. Common examples are driving piezo actuators, MEMS, OLEDs, liquid crystals, etc.

EMC Scanners

The Swedish company Detectus is a world-leading supplier of EMC-Scanner products, since the 1990’s. As from July 2020, the Detectus company is an integral part of Pendulum Instruments.

The Pendulum/Detectus series of EMC-Scanners are powerful pre-compliance tools for measurement and analysis of Electro-Magnetic Interference (EMI). The Scanners feature repetitive high-resolution scanning of emission (and optionally also immunity) down to 25 μm steps. You can even scan inside an IC (option).

Detectus SCN-500 series

The SCN-500 series comes in three sizes and can be two- or four dimensional. Each model can be equipped with a 3, 6 or 10 GHz probe kit.

Detectus HRE series high-resolution scanners with 3D or 4D scanning

The HRE series combine ultra-high scan resolution of 25 μm with probe head rotation, and the best-in-class scanning SW to deliver powerful visualization of the EMC test. An optional IC scan kit, with dedicated inspection camera and high resolution near-field probes, lets you even scan for emission and immunity hotspots inside an IC.
