Universal Preamplifier 14
UP14
-
For Two Dimensional Magnetic Recording (TDMR) and Heat-assisted Magnetic Recording (HAMR) Headamplifiers. Universal Preamplifier 14 (UP14) is designed for TDMR and HAMR Head Amplifiers. With new Guzik RWA4000 TDMR, UP14 allows to process signals from three Read Channels. It also supports two high speed data channels for Write data and Laser data. UP14 has two channels for dynamic TFC control and allows to program TFC power per sector and close loop TFC power control in each channel. UP14 can generate two programmable modulation signals for write data and laser data with bandwidth up to 20 MHz. UP14 consist of two boards. The first UP14 RW Board processes high-frequency signals: read-back signals, write data and laser data. The second UP14 Control Board provides power, control and low-frequency signal generation: TFC, write data modulation and laser modulation.

External Pre-amplifiers
-
Although all Spectrum A/D cards have a very powerful input section with a highly configurable input amplifier and a variety of input ranges it is sometimes necessary to have additional external amplifiers if the signal to acquire has an extremely low level. Spectrum offers a range of perfectly matching external amplifiers to cover such cases. These powerful amplifiers have been rated using the Spectrum cards and offer best performance together with high amplification rates.The amplifiers are simply connected between the signal source and the Spectrum A/D card input and can be manually switched between different settings using small lever keys. All amplifiers allow the offset compensation by using an adjustable screw.

RX Pre-Amplifier System
RAM-34
-
The RAM-34 is a complete pre-amplifier system designed primarily for the low bands 160M thru 40M. It has inputs for four receive antennas and internal 3-pole bandpass filters for 160M, 80M and 40M. In addition to the pre-amplifier, it has a step attenuator that togetherwith the amplifier stage provides gains from -20 dB to +20 dB in 5 dB steps. This allows equalizing the signal levels between the antenna inputs. Gain settings are memorized for each antenna on each band. Different types of receive antennas have different signal levels and the gain memories eliminate the need to adjust the receiver or pre-amplifier when switching between the antennas.
