L3Harris NARDA PMM ER8000 User Manual page 56

Following are Commands to control and set various operating modes of PMM
7.6 PMM ER8000
ER8000, that can be distinguished in two main groups:
COMMANDs
7.6.1 Query
COMMANDs
?3PR This query command #?3PR * sends back a string expressing whether the
apparatus is a PMM ER8000 and in which mode. The reply is either:
?AAT This query command #?AAT * sends back a string expressing the Attenuator status
for Analyzer mode. The reply is made of 2 fields:
Example of reply: AAT =AUTO; 20 which means that the Attenuator is now
switched to 20dB automatically by ER8000
?ACE This query command #?ACE* sends back a string expressing the Center
frequency, in exponential notation, for analyzer mode. Unit is fixed MHz.
Example of reply: ACE = 1.500000e+07 which means that the Center frequency in
Analyzer mode is 15MHz
?ADT This query command #?ADT * sends back a string expressing the detector used for
Analyzer mode. The reply cab be:
?AHT This query command #?AHT* sends back a string expressing the HOLD TIME for
Analyzer mode. Unit is fixed ms.
Example of reply: AHT= 1000 ms which means that the hold time in Analyzer mode
is 1000ms (or 1s)
?AOP This query command #?AOP* sends back a string expressing the Stop frequency,
in exponential notation, for analyzer mode. Unit is fixed MHz.
Example of reply: AOP = 3.000000e+07 which means that the Stop frequency in
Analyzer mode is 30MHz
?ART This query command #?ART* sends back a string expressing the Start frequency,
in exponential notation, for analyzer mode. Unit is fixed MHz.
Example of reply: ART = 1.500000e+07 which means that the start frequency in
Analyzer mode is 15MHz
?ASP This query command #?ASP* sends back a string expressing the Spanfrequency,
in exponential notation, for analyzer mode. Unit is fixed MHz.
Example of reply: ASP = 3.000000e+07 which means that the Span frequency in
Analyzer mode is 30MHz
