Topic starter  

Low Frequency Preamplifier up to 60MHz. Works with any brand of Spectrum Analyzers and directly fits to any SPECTRAN. Broadband sensitivity increase by up to 25dB.

The UBBV NF series provides a high impedance input signal and therefore can be operated even with the antennas of the MagnoTRACKER series or other regular 50 ohm devices. The calibration data of the preamplifier are also stored in the Spectrum Analyzer Software "MCS".

The UBBV-NF can be operated via an internal battery (running time approx 3-4 hours) or via the included AC adapter. Via the USB port it´s possible to read the calibration data of the preamplifier, which are stored in the internal EEPROM and so can not be lost.

A "must have" to get the maximum performance out of any SPECTRAN unit.

When I connect the UBVNF25 to a DAQ (MCC: UBS-1602HS) without any input, I get a DC component of 0.625 V ... How can this DC component be removed ? (Same issue on the battery only or with the external charger)
The MCS software allows just to extract data , is there a way to calibrate the device and remove the DC signal ?
