Overview
Table 1.3.1-1 Specifications for MP1862A (Cont’d)
Item Specifications Remarks
Data Input Number of Input 2 (Data/
Data
Input) (Differential)
Input Conditions Selectable from Single-ended 50
Differential
50
, or Differential 100
Data or XData can be set to input for
Single-ended interface.
Tracking, Independent, or Alternate can be set
for Differential Interface.
When setting to Alternate, Data-XData or
XData-Data can be set.(Only when absolute
difference between Data Threshold and XData
Threshold is 3.0 V or less)

When Variable is selected for Termination:
–2.5 to +3.5 V /0.01V step
Connector V (f.)
*1: Defined based on the condition where Single-ended 50
is selected.
*2: Defined under the following test pattern conditions:
• PRBS2^31–1
• Mark Ratio1/2
*3: Defined in the temperature range of 20 to 30°C.
*4: Defined by looping back a signal through J1600A coaxial cable,
41V-6 fixed attenuator, and MP1861A.
*5: The input amplitude corresponds to the operating range of the
Auto Search and Auto Measurement functions, and the lower limit
for the input amplitude is defined by Eye Height.
*6: This is determined by Eye Height.
The output amplitude must be that of MP1861A + ATT with an
error rate being “1E–9” or lower in the following measuring system
(a sampling oscilloscope with more than 70 GHz bandwidth is used
for output amplitude observations).
