Description

The 9250 is a bench-top, 2U, half 19” rack size, fully metal case dual channel amplifier. The instrument can be configured to be used as two, single-ended independent channels, or as a one input with two differential outputs. The amplifier case was designed to stack on top or below other Tabor products. It also can be mounted alongside a Tabor generator in a standard 19" rack. The waveform-amplifier combo is an ideal solution for virtually any high-voltage, wide bandwidth application.

    Large signal bandwidth to 15 MHz

    Small signal bandwidth to 30 MHz

    High amplitude to 40Vp-p (into high impedance)

    Slew rate to 200V/µs

    Low distortion

    Custom Configuration of:
         Gain
         Input impedance
         Output impedance
         Output configuration

Input Characteristics
The inputs to the amplifiers be configured to match different source impedances such as 50Ù, 75Ù, or 1MÙ and the outputs can be configured to match different load impedances such as 50Ù, 75Ù, or 600Ù. There are three inputs for each channel:

Output Characteristics
The outputs are located on the front panel. There are two outputs, one for each channel. When the 9250 is configured as two separate amplifiers, the outputs generate amplified signals within the range of 40Vp-p into open circuit or 20Vp-p into matching load impedance. The bandwidth of the outputs is around 20MHz for large signals. Small signal bandwidth can reach 50MHz.

Instrument Configuration
The 9250 can be configured as a differential amplifier. In this case, the channel 2 input is disabled and channel 1 input is amplified and distributed differentially to both outputs. In this case, channel 1 output generates in-phase signal while channel 2 outputs an inverted signal that has exactly 180 phase offset to the normal output. Full amplitude and bandwidth is preserved when the 9250 operates in differential mode. The output impedance of the differential outputs is modified to 25Ù, 37.5Ù, or 300Ù for differential drive of 50Ù, 75Ù, or 600Ù loads. Using the differential mode, the 9250 does not sacrifice accuracy, nor does it sacrifice bandwidth.

Auxiliaries
The 9250 has two additional inputs for each channel allowing summation of two signals and providing an external control of DC level offset. These inputs are accessible from the rear panel only.
