Model N6705 Service Guide
Keysight 3458A and the current measured over the interface.
Readings should be within limits specified for the appropriate model
under "Current Readback, 200µA Range".
8
For models N6763A–N6766A, and N6783A only. Set the current
measurement to the low range. Set the instrument as described
under "Current Readback, Low Current". Repeat step 5. Record the
current measured over the interface. The readings should be within
the limits specified under "Low Current Readback Low Range".
9
Steps 9 and 10 for models N6781A, N6782A, N6784A only. Connect
the Keysight 3458A directly across the output (see Test Setup D
without the resistor). Set the Keysight 3458A to the 100 mA range
(no autoranging). Set the current programming to the low ranges -
300 mA for N6781A and N6782A; 100 mA for the N6784A, . Set the
instrument as described under "Current Programming 300 mA & 100
mA ranges". Record the current readings of the 3458A. The readings
should be within the limits specified under "300 mA and 100 mA
range Current Iout".
10 Set the current programming to the 10 mA range for the N6784A.
Set the instrument as described under "Current Programming 10 mA
range". Record the current reading of the 3458A. The reading should
be within the limits specified under "10 mA range Current Iout".
11 Steps 11 and 12 for models N6781A, N6782A, N6784A, N6785A,
and N6786A only. Connect the Keysight 3458A in series with a 10 Ω
resistor to the output (see Test Setup D). Set the Keysight 3458A to
measure current using the 100 mA range. Set the current
measurement to the 100 mA range. Set the instrument as described
under "Current Readback 100 mA Range". Record the current
reading of the 3458A and the current measured over the interface.
The readings should be within the limits specified under "100 mA
Range Readback".
12 Connect the Keysight 3458A in series with a 10 kΩ resistor to the
output (see Test Setup D). Set the Keysight 3458A to measure
current using the 10 mA range. Set the current measurement to the
1 mA range. Set the instrument as described under "Current
Readback 1 mA Range". Record the current reading of the 3458A
and the current measured over the interface. The readings should be
within the limits specified under "1 mA Range Readback".
13 For models N6781A, N6782A, and N6784A only. Connect the
Keysight 3458A in series with a 1 MΩ resistor to the output (see Test
Setup D). Set the Keysight 3458A to measure current using the 100
μA range. The remote command is "DCI 100e-6". Set the current
measurement to the 10 µA range. Set the instrument as described
under "Current Readback, 10 µA Range". Record the current reading
of the 3458A and the current measured over the interface. The
readings should be within the limits specified under "10 µA Range
Readback".
