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.

(1) Custom configuration may change amplifier      characteristics, and may affect minimum quantity,      price and delivery time. Please contact the factory for a      quotation before placing an order for any configuration      other than standard. (2) Custom gain from x10 to x20 can be ordered however,      bandwidth may change. (3) Output impedance for differential drive is 600W only. Note: Options must be specified at the time of your purchase.
