Figure E,15: Time Difference Between Signals and SYNC Signals

Time Difference from Markers. Markers are written as data into waveform memory in the same manner as waveform data, but since the waveform goes through amplifiers and other elements, it is output somewhat after the marker. Applying a filter to the waveform increases this time delay. This delay is about the same as the delays relative to the sync signals given in Table E-3.

X5 Amplifier When the output amplitude is 0.501 V or greater, a x5 amplifier is inserted in the signal path. The waveform is affected by passing through this x5 amp, and some error is generated. If high precision waveform output is required, hold the output amplitude below 0.501 V.

Attenuator This block comprises two ±3 dB attenuators, one ±10 dB attenuator, and one ±20 dB attenuator.

Including the amount that the DAC reference voltage can be changed, a total of 40 dB of attenuation is possible. Figure E-16 shows the attenuator configuration.
