Note: BITE = 0 is an indication of Atomic Lock (1 = un-Lock)
Analog Tuning = 0 indicates that it is turned off (1 = on)

Retrieves the telemetry headers. Response is a comma-delimited string, suitable for
importing into spreadsheet programs.

(0.1mv),DDS Frequency Center Current (0.01Hz),CellHeaterCurrent
(ma),DCSignal(mv),Temperature (mDegC),Digital Tuning

Retrieves the telemetry values. Response is a comma-delimited string, suitable for
importing into spreadsheet programs.
Example Response:
0,V1.0.4,1801MX00041,55173,20174,0,413,1000,55306,3,0,1450,3000

Note: Maximum output string length = 128 characters.
Note: Similar functionality (comma-separated headers and values) is available
with the C3 commands using
{browse,name}
and
{browse,value}
.
<NX0>
The command disables analog tuning and persists the setting past power-off. See the
A
command for a non-persistent version.
<NX1>
The command enables Analog Tuning and persists the setting past power-off.
<FA>
This command has essentially the same function as the new
latch
command. Previ-
ously, for the legacy MAC-SA3x, the purpose of this command was to add the digital
adjustment value into the current center frequency value so that the accumulated
changes can be saved. The center frequency could then be subsequently saved using
the
<FS>
command, if the changes were to be made permanent (this step is no longer
necessary because
<FA>
now saves the value to NVRAM). Upon execution of
<FA>
,
the digital adjustment will be re-set to zero.
<FS>
Save the current DDS center frequency to non-volatile memory (NVRAM). The
<FS>
command can be used to persist the setting of the DDS center frequency. However,
there is no way to persist digital adjustment, per se. The recommend procedure to
"persist" digital adjustment is to use the
<FA>
command to alter the DDS center fre-
quency and set the digital adjustment to zero and then use the
<FS>
command to save
the DDS center frequency. As the default value of the digital adjustment is zero, this
effectively saves the value.
Note: This command is redundant with the
<FA>
command when used on
MAC-SA5X because the
<FA>
command also saves the value to NVRAM.
