Output Pulse Clock Speed - Aerotech MXH Series Hardware Manual

Introduction

1.5. Output Pulse Clock Speed

The output sine and cosine pulse trains are interpolated to spread out the pulses evenly throughout the .5 µs
sample period. The output pulse can be clocked at four different frequencies depending on the input
frequency and the pulse width jumper settings. The output clock can be 4 MHz, 8 MHz, 16 MHz, or 32 MHz.
The following chart in Figure 1-8
Sixteen counts per .5 µ second sample period generates the maximum of 32 million counts per second.
