7-6 Remote control
?LSN
This query command
#?LSN*
sends back a string showing which Band B input is
selected in the format: LSN=
n
Where
n
can be:
•
0

Input on N connector
•
1  Input on ER8000 internal LISN L1
•
2  Input on ER8000 internal LISN L2
Example of reply
: LSN=0
?MAF This query command #?MAF* sends back a string expressing the tuning frequency,
in exponential notation, for manual mode. Unit is fixed MHz.
Example of reply
: MAF= 1.07 which means that the tuned frequency in
manual mode is 15MHz
?MAT This query command #?MAT * sends back a string expressing the Attenuator
status for Manual mode. The reply is made of 2 fields:
•
MAT=AUTO ( ER8000 automatically selects the most suitable attenuator to
get best dynamic range) or MAT=MAN ( the operator selects manually the
attenuator)
•
Value (in dB) of current attenuator
Example of reply
: MAT=AUTO; 20 which means that the Attenuator is now
switched to 20dB automatically by ER8000
?MHT This query command #?MHT* sends back a string expressing the HOLD TIME for
manual mode. Unit is fixed ms.
Example of reply
: MHT= 1000 ms which means that the hold time in manual mode
is 1000ms (or 1s)
?RBW
This query command #?RBW * sends back a string expressing the selected RBW.
The reply is made of 3 fields:
1. RBW=AUTO ( ER8000 automatically selects the suitable RBW according
the tuned frequency) or
RBW=MAN
( Operator selects manually the RBW)
2. Id identify the RBW as follows:
o
1

300kHz
o
2  100kHz
o
3  30kHz
o
4  10kHz
o
5

3kHz
o
6

9kHz (Cispr 16-1)
o
7

200Hz (Cispr 16-1)
o
8  1kHz
o
Only for C, D band or > 30 MHz
 10  120kHz (Cispr 16-1) (Opt. 01)

9

1MHz (Opt. 01)
3. RBW NickName (a mnemonic name)
Example of reply
: RBW=AUTO 6 (9k_CISPR) which means that selection is
automatically made by ER8000, the RBW id is 6 ( 9kHz (Cispr 16-1). (9k_CISPR)
is the nickname to quickly identify it
?S/N
This query command #?S/N* sends back a string containing serial number
internally stored by manufacturer.
Example of reply: S/N=000WE50327
