Keysight 5500 SPM User’s Guide 5-6
In this diagram the numbers refer to the slots in which the lock-in cards
sit inside the MAC III box. Lock-ins 1, 2 and 3 are located in slots 1, 3
and 5, respectively. The connections are as follows:
AUXIN 1-5 AUX inputs for each slot. AUXIN 1, 3 and 5
are the AUX inputs for Lock-ins 1, 2 and 3,
respectively.
Drive 1-5 The drive outputs from each slot. DRIVE 1, 3
and 5 are the Drive Out signals for Lock-ins
1, 2 and 3, respectively.
Drive_In A single drive line that can optionally be
summed in to any or all of the drives by
using Sum External Drive on the Lock-in
tab of the Advanced AC Modes window.
SP_RX and SP_TX lines These serial lines are not currently used.
Once all connections have been made it is safe to turn on power to all
components.
Hardware and Sample Setup
Most hardware and sample setup options with MAC III are identical to
those for standard AAC and MAC Mode operation, as covered in
Chapter 6 , “AC Modes.” Please refer to Chapter 6 for the steps required
to set up the microscope for imaging. Note the phase conversion
coefficient is 18 ° per volt for the MAC III controller.
Auxiliary Signal Access Box
An optional signal access box is available for MAC III to allow custom
multi-frequency experimentation. The Auxiliary Signal Access Box
(ASAB) can be used in the development of novel capabilities for the
examination of local mechanical and electromagnetic properties. The
box is shown in
Figure 11-4 and described in Table 4 . Specific examples
