Input Resistance Characteristics - HP -7035B Technical Manual

saturate the amplifier's output stage causing an increased
dead zone and decreased pen speed. Pen oscillation may
also result if the noise "beats" with the servo system's carrier
frequency. A built-in low pass filter in both axes minimizes the
effects of normal mode noise. The response of this filter is
illustrated in Figure 1-7.

1-35. Figure 1-8 indicates the typical frequency response for a
sinusoidal input. Although the recorder is designed to record
slowly varying dc voltages, ac voltages up to a few Hz can be
recorded.
