Model ASC-50

Certified

Description

Frequency Devices’ ASC-50, is a laboratory bench-top

programmable instrument that combines familiar

analog signal input and output with the power and

flexibility of DSP. The ASC-50 provides the user with

finger-tip control of filter type, (low-pass, high-pass,

band-pass, and band-reject), operating frequency,

pole/bandwidth configuration, pre and post gain

settings, and analog/DSP filter functions - including

many not available through conventional analog

techniques. All are accessible at the touch of a button.

With a frequency range from 0.1Hz to 30kHz

combined with amplitude response of Butterworth,

Chebychev, elliptic and finite-impulse-response (FIR)

filter functions, the ASC-50 offers wide tuning flexibility

without the need for pre-defined programming.

An analog instrumentation interface provides input

gain; DC offset control and variable output gain along

with selectable single-ended and differential inputs to

accommodate a variety of driving signals. Additionally,

input DC-offset control is provided with expanded

resolution. With the exception of filter and frequency

changes all parameters of the ASC-50 can be altered

on the fly without halting signal flow. Real-time bypass

and gain-control facilitate test comparisons with and

without the filter activated.

A four button touch-pad coupled with a liquid-crystal

display (LCD) affords the user complete control of

various signal conditioning functions. Through the

LCD, the operator is prompted by a selection of

several filter types, functions, frequency and gain

settings. Less than optimum selections are indicated,

providing guidance without regimentation. Saturation

(over-range) conditions are indicated on both the input

and output permitting ease of system setup and use.

Features

• Wide variety of filter types, functions and

frequencies

• Precise, stable filter performance

• Adjustable gain and attenuation

• DC offset control

• Choice of single or differential inputs

• Special DSP bypass

• Analog and DSP clip indicators

• Filter performance display
