Filters

The dS-LPF is a passive 20kHz low-pass filter in 2 or 4-channel configurations designed primarily for measuring digital power amplifiers. The Passive Low-pass Filter is intended to aid measurement of switching ('Class D', or 'PWM') power amplifiers where the presence of shaped and switching noise outside the audio band can adversely affect the ...more

Class D amplifiers use a switching process that adds fast-rising edges at the switching frequency to the audio output signal, presenting a difficult signal for audio analysis. The solution is to precondition the signal before presentation to the analyzer using a low-pass filter that reduces the out-of-band switching components (the fast edges) ...more

The 6165 is a two-channel amplifier-filter module. Each channel has isolated input, 50 kHz bandwidth and two outputs that can be filtered or wideband. Bandwidth of 100 kHz is optional. The input is two-wire shielded and is isolated from the outputs, power and control interface. This gives the user complete freedom to ground the input without c ...more
