Syntax: 

DEFAULT:

 

Compatible commands: 

Level Adjust 
 

LEVEL:GAIN 

 

LEVEL:DET   

 

(Not available on all models) 

 

LEVEL:THR   

 

(Not available on all models) 

 

LEVEL:RESP  

 

(Not available on all models) 

Mode Select 
 

MODE:MANUAL 

 

(Not available on all models) 

 

MODE:PULSE 

 

(Not available on all models) 

 

MODE:ALC<space>INT 

(Not available on all models) 

 

MODE:ALC<space>EXT 

(Not available on all models) 

NOTES: 
1.

 

Use the command 

DEFAULT:FACTORY

 to reset all applicable settings back to their factory defaults. 

2.

 

All applicable defaults can be queried, except 

DEFAULT:FACTORY

, by adding a ? character in place 

of the setting parameter. 

3.

 

If the ALC Lockout Feature (not available on all models) is engaged, the default ALC values set with this 

command will not be used. 

Example 1: 

To set the default RF Gain to 75%, send the following command: 

 

 

DEFAULT:LEVEL:GAIN75<LF> 

Example 2: 

To query the default RF Gain setting, send the following command: 

 

 

DEFAULT:LEVEL:GAIN?<LF> 

Response: 

DEFAULT:LEVEL:GAIN75<LF> 

Example 3: 

To set the default mode to manual, send the following command: 

 

 

DEFAULT:MODE:MANUAL<LF>

 

2.4.7 

Interlocks  

The 175A400 has one interlock circuit that is wired to the rear panel Safety Interlock connector. This 

interlock requires a normally closed external circuit to allow the unit to function.
