OPERATION AND CONTROLS

common with chassis ground by connecting the "AMP GROUND" and "CHASSIS GROUND" banana jacks on the rear panel of the SR560. When connected to AC power, the chassis of the unit is always connected to the grounding conductor of the AC power cord. The inputs are protected to 100 VDC but the DC input should never exceed 10 Vp. The maximum DC input before overload is 1 V peak.

The COUPLING pushbutton selects the method of connecting the A and B inputs to the amplifier. The inputs can be AC (0.03 Hz - 3 dB) or DC-coupled, or the inputs to the amplifier can be internally grounded with the A and B input BNC’s left floating.This feature makes for simple offset nulling, particularly useful when operating the amplifier DC-coupled at high gains. Please refer to CALIBRATION AND REPAIR -- OFFSET ADJUSTMENT for information on the offset nulling procedure.

NOTE: When the coupling is set to AC, a

0.03Hz cutoff high-pass filter is always

engaged. All high-pass filter modes can still be selected while AC-coupled, but the 0.03 Hz filter will always be in, even if the filters are set to DC. Because one of the two filter sections is always used as a high pass when AC coupling is selected, low-pass filters are only available with a 6 dB / octave rolloff.

The INVERT pushbutton allows the user to invert the output of the instrument with respect to the input when operating with single-ended or differential inputs. The INVERT LED displays the output sense relative to the input for all SOURCE settings.

Filters

The SR560 contains two identical 1st-order R-C filters whose cutoff frequencies and topology (high-pass or low-pass) are controlled from the front panel. The maximum bandwidth of the instrument is 1

MHz. The filters in the FILTER CUTOFFS section can be configured in the following six ways:

i.high-pass filter at +12 dB / octave

ii.high-pass filter at +6 dB / octave

iii.high-pass filter at +6 dB / octave, and low-pass filter at -6 dB / octave (band-pass)

iv.low-pass filter at -6 dB / octave

v.low-pass filter at -12 dB / octave

vi.no filters in the signal path

The filter settings are controlled by the ROLLOFF, HIGH-PASS and LOW-PASS pushbuttons. Each time the ROLLOFF pushbutton is pressed the instrument configures the two R-C filters to conform to the progression shown above. The four ROLLOFF LED’s give a visual indication of the current filter configuration. For the HIGH-PASS filter the left pushbutton serves to decrease its cutoff frequency. The two pushbuttons for the LOW-PASS filter function in an analogous manner.

When the FILTER CUTOFFS section is configured solely as high-pass or low-pass (i, ii, iv and v ), the cutoff frequency is illuminated by one of sixteen LED’s in the range from 0.03 Hz to 1 MHz, and the slope of the rolloff is shown by one of the four ROLLOFF LED’s. When the filter section is configured as band-pass (iii), the cutoff frequencies are illuminated by two LED’s. The frequency setting on the left marks the cutoff for the high-pass filter, and the setting on the right is the cutoff for the low-pass filter. The two 6 dB / oct ROLLOFF LED’s are also illuminated. In this case the two cutoffs can be set to the same frequency to provide a narrow bandpass. When both filters are removed from the signal path (vi) all rolloff and cutoff frequency LED’s are extinguished from the FILTER CUTOFFS section and the DC LED is on.

NOTE: High pass filters are not available for the four highest frequency settings. See the note under Source: Coupling for
