To Configure The Voltage Reference - Agilent Technologies E5900B User Manual

CAUTION:
Configuring the Emulation Probe

To configure the voltage reference

The emulation probe uses the Target_VDD signal on the JTAG connector to
determine logic high and logic low levels when driving the TDI and TCK
signals.
Voltage Reference Configuration
Value Meaning
external The voltage reference is generated by the
target system.(Default)
value The voltage reference of value is generated
internally by the emulation probe. The value
is a number followed by either mV, which
indicates the value is in millivolts, or V, which
indicates the value is in volts.
This option should only be used if the core voltage is different than that of the
Vref signal on the JTAG connector. Use this option with extreme care,
because it is possible to damage the target system if the voltage level is chosen
incorrectly.
