measurement
function *

Channel tracking: Makes the following settings dependent on Channel 1.
• Bit rate
• PPG pattern
• PPG/ED tracking
• Measurement mode
BER measurement:
Collectively starts and stops the measurement for ED1 to ED4.
All channel BER result display:
Displays the measurement results of ED1 to ED4 at a time.
*1: Measurement accuracy depends on the internal reference clock.
*2: This can be set when measurement cycle is single or repeat
*3: This can be set when test pattern is Programmable Pattern and data
length is 128 bits or more.
*4: Only Option 014
