4417A 射頻錄制儀 http://yh200.com.cn/archives/450 http://yh200.com.cn/archives/450#respond Tue, 08 Aug 2017 12:09:14 +0000 http://t24.izt8.com/?p=450

This device can record RF signals in various points of fields. When reproducing the signal data in factories or laboratories, it is possible to test receivers under the reception environment of the data.

 

 

– Compact size and all-in-one model. The recording part and the reproduction part are equipped to one body. (Approx 15 kg)

– The frequency range covers 30MHz to 3000 MHz of the recording frequency, so that this device can record and reproduce an RF signal of all terrestrial broadcast and all satellite broadcast in the world.

– 8 MHz, 24 MHz, 40 MHz and 54 MHz bandwidth RF signal can be recorded/reproduced.

– A touch panel (Seven-inch) is equipped, so that this device provides user interface having excellent operability and visibility.

– The solid-state-drive (SSD) for the data recorder is equipped (Data of 180 minutes can be recorded/reproduced at 8 MHz bandwidth captured and data of 30 minute can be recorded/reproduced at 54 MHz bandwidth captured.)

– Data can be backed up at high speed through eSATA port and USB2.0 port.

– The Low Noise Amplifier is equipped to the RF input side, so that low electric field can be adopted.

– Auto Cal function that sets the level of the recorded signal automatically at the RF signal capturing is equipped.

– Remote control, time recording function and repeat reproduction function are equipped.

– GPS module is equipped, so that the position data at the recording can be inserted to the recorded data. Data can be controlled easily.

– The frequency and level at the recording can set automatically at the reproduction .

– This device can reproduce the data captured by Eiden’s existing RF captures (4406A, 4411A, 4412A and 4416A), so that old data can be used effectively.

– It corresponds to RF record and reproduction under diversity environment by using two or more sets.

– Inversion function of RF polarity at the reproduction is equipped.

– Data in ATSCA-74 standard can be reproduced.

4420A 射頻錄制儀 http://yh200.com.cn/archives/447 http://yh200.com.cn/archives/447#respond Tue, 08 Aug 2017 12:08:20 +0000 http://t24.izt8.com/?p=447

This device can record an RF signal in the fields and the recorded data can be taken out. Then , they can be reproduced in factories or laboratories. Therefore, operations of receivers can be confirmed under the receiving condition that is as same as the fields.

 

– The device is designed as compact size and light weight and equips the record part and the reproduction part. (A PC for the control and SSD or HDD in RAID configuration are needed other than the main body ) Features (A PC for the control and SSD or HDD in RAID configuration are needed other than the main body.) – This device can be used under DC +12 V when using the DC-DC adaptor of the option. (Prepare external batteries separately.)

– This device corresponds to the frequency in the range from 450 kHz to 1000 MHz. (The frequency in the range from 50kHz to 30MHz and from 1000MHz to 3000MHz is possible by carrying the option.)

– The frequency band can be chosen from “8 MHz”, “24 MHz”, “40 MHz” or “54 MHz”. (In the cases of “40 MHz” and “54 MHz”, only the half rate mode can be used.) (*2)

– If the 6TByte HDD of the option is used, the recording time of the 8 MHz band is 36 hours.

– This device is controlled from the PC The user interface provides excellen This device is controlled from the PC. The user interface provides excellent operability and visibility operability and visibility.

– The spectrum can be displayed. Therefore, the signal can be recorded while the spectrum is confirmed. – A Low Noise Amplifier is equipped for the RF input. Therefore, this device corresponds to the weak electric field.

– The Auto Cal function that sets the level at the recording automatically when the RF signal is captured is equipped.

– The time and the location information can be buried into the recorded data, when using the GPS antenna of the option. Therefore, the recording route and the signal level at the points can be displayed on the map, if the dedicated software is used.

– This device can share existing data captured by existing devices. Therefore, old data can be used effectively.

– This device sets the frequency and the level at the recording automaticall This device sets the frequency and the level at the recording automatically when reproducing the data. when reproducing the data.

– This device equips the inversion function of the polarity at the reproduction.

– This device can reproduce data of A74 standard in ATSC.
