ビジネスシステム Product Lineup

This is a UHF band frequency converter that constitutes part of a phase adjuster system. It converts input frequencies from UHF channel 13 to channel 62 to the required frequency for the phase difference measurement section. It consists of two systems of 75Ω-50Ω impedance conversion circuits, high-frequency amplification circuits, frequency conversion circuits, BPF, output circuits, a LOCAL signal generation circuit, and a DC power supply circuit. It connects to a PC via a USB cable, and the frequency and output level are set using a frequency setting app (mini GPS Clock Configuration) for operation. ● The input frequency supports UHF channels 13 to 62. ● The frequency setting PC app allows for easy configuration of frequency and output levels. Additionally, the set frequency is stored in internal ROM, so it can operate at the configured frequency even when disconnected from the PC. ● The operating power supply is AC100V. There is a +5V output connector on the back of the device, which can be used as a power supply for the phase adjuster used simultaneously.

• High frequency/microwave parts

● It consists of a USRP GPIO-compatible adapter board and a BS3G30A RF digital step attenuator, which can be directly controlled from the NI USRP X300_X310. ● The BS3G30A RF digital step attenuator has a wide operating frequency range from DC to 3GHz, and in this system, the attenuation can be controlled in 0.5dB steps up to 31.5dB using 6-bit parallel control.

This is a practical model implemented in a shielded case, enhancing measures against signal leakage to the outside and external interference signals. The control connector is also covered with a shielded cover, strengthening measures against spatial noise signals. Measures against conductive noise via control lines are implemented using ferrite beads. ● The attenuation can be varied in 0.5dB steps up to a maximum of 31.5dB. ● The operating frequency is broad, ranging from DC to 3GHz. ● The attenuator device used is SKYWORKS' SKY12347-362LF. ● The operating voltage is +3.3V or +5V. ● Control is possible via TTL/CMOS in 6-bit serial or parallel.

The BS3G30SEVZ is an evaluation and practical system that combines the BS3G30 RF digital step attenuator, the BS3G30S serial control board, and the necessary cables. It allows remote control of the attenuator from a PC, enabling the construction of an automated measurement system. The attenuation can be varied in 0.5dB steps up to a maximum of 31.5dB. Power is supplied via USB, so no external power source is required. The PC application for this serial control board operates on the following operating systems: - Windows XP, 7, 8.1 *Windows is a registered trademark of Microsoft Corporation.

● It can be combined with BS3G30 to adjust the attenuation in 0.5dB steps up to a maximum of 31.5dB. ● The power is supplied via USB, so no external power supply is required. ● One board can control two BS3G30 step attenuators. ● The PC application for this serial control board operates on the following OS: - Windows XP, 7, 8.1 *Windows is a registered trademark of Microsoft Corporation.

• High frequency/microwave parts

● By combining with BS3G30, the attenuation can be varied in 0.5dB steps up to a maximum of 31.5dB. ● This board operates with a single +5V power supply. ● A +5V AC adapter is not included, so please prepare one that is compatible with the specifications of this board.

• High frequency/microwave parts

● The attenuation can be varied up to a maximum of 31.5 dB in 0.5 dB steps. ● The operating frequency is wideband from DC to 3 GHz. ● The attenuator device uses SKYWORKS' SKY12347-362LF. ● The operating voltage is +3.3V or +5V. ● It can be controlled via TTL/CMOS in 6-bit serial or parallel. ● It is designed to facilitate the easy construction of evaluation and test attenuators for the device.

It demonstrates its effectiveness in the adjustment and testing of high-frequency devices from the VHF band to the UHF band. Measurements can be made not only for CW but also for modulated signals such as FM, PM, and OFDM. The measurement frequency is a specified single wave. An option allows for the specification of up to ten frequencies (available only for MP-900BS).
