When the annunciator is flashing, press or to step through the available
frequencies.
While the annunciator is flashing, press or to set the voltage amplitude, or
to step through the available duty cycle values or pulse width values.
Press Sweep to cycle through the ramp and scan sweep functions, or to disable the sweep
mode for the selected output (CV or CC).
[4]
See “Sweep Functions” on page 93 for more
information.
Press Shift > Limit to set the overcurrent limit value for the CV output or the overvoltage
limit value for the CC output. See “Protection Functions” on page 78 for more information.
Press Shift > Protect to set the overcurrent protection value for the CV output or the
overvoltage protection value for the CC output. See “Protection Functions” on page 78 for
more information.
Press Shift > Range to toggle between range S1 (30 V/1 A) and range S2 (8 V/3 A).
[5]
See
“Selecting a Range” on page 97 for more information.
Press to toggle between source output (OUT) and source standby (SBY). See
“Enabling the Output” on page 98 for more information.
Press Shift > EXT to enable remote sensing. See “Remote Sensing” on page 99 for more
information.
[1] The voltage path is the default path when you select the frequency measurement function. To switch to the current path for
frequency, pulse width, and duty cycle measurements, first press , then press Hz ms %.
[2] The refresh hold variation and threshold values can be configured through the utility menu. See Chapter 4, “System Related
Operation,” starting on page 107 for more information on the utility menu.
[3] The continuity and diode test functions have a fixed 4½ digit resolution. Capacitance measurement is fixed to 3½ digit
resolution.
[4] The sweep functions can only be accessed when the U3606A is in constant voltage or constant current mode. You cannot
access the sweep functions while the U3606A is in square-wave output mode.
[5] You can only change the range when the instrument output is in the “standby” state (the SBY annunciator is illuminated).
