Example 4: Attenuator Groups
In this example, we will use four attenuators to create an attenuator group. We will use the following devices:
Attenuator #1: Model 3200T-1, serial number 101
Attenuator #2: Model 3200T-1, serial number 102
Attenuator #3: Model 3200T-1, serial number 103
Attenuator #4: Model 3200T-1, serial number 104
We will use the names ’AT1’ thru ’AT4’ for these attenuators, and we will name the resulting group ’GROUP1’
a. Assign names to the four attenuators.
Send:
ASSIGN AT1 ’3200T-1’ 101
ASSIGN AT2 ’3200T-1’ 102
ASSIGN AT3 ’3200T-1’ 103
ASSIGN AT4 ’3200T-1’ 104
b. Assign a name to the group
Send:
GROUP GROUP1 AT1 AT2 AT3 AT4
c. Save these names in the non-volatile EEPROM memory.
Send: SAVE
ASSIGN
SAVE GROUP
d. Rerun the device assignment to associate the newly defined names with the attenuators.
Send: REASSIGN
The channels may now be programmed using the following commands as examples:
ATTN AT1 70 ; sets the 1st attenuator (serial number 101) to 70 dB
ATTN AT2 5 ; sets the 2nd attenuator (serial number 102) to 5 dB
ATTN GROUP1 32 ; sets each of the four attenuators (AT1-AT4) to 32 dB
INCR GROUP1 ; increments the attenuation setting for each attenuator on the group (32+1=33dB)
ATTN? AT1 ; returns ’33.00’
STEPSIZE GROUP1 5 ; sets the increment size to 5 dB
DECR GROUP1 ; decrements the attenuation setting for each attenuator on the group (33-5=28dB)
ATTN? AT1 ; returns ’28.00’
As before, steps a) thru d) do not need to be repeated unless there is a change in the physical system configuration.
The names will be automatically assigned during the power-on configuration process.
