Revision B 

 

 

This  unit  is  7.4U  high,  16.75

”  width.  With  the  handles  removed  it  will  fit  into  a 

standard rack. 
 

2.2.1 Mains Voltage 

 
The unit accommodates AC line voltages from 100 TO 240 VAC 47 

– 63 Hz.  

 

2.3 OPERATION 

 
A fixed line cord is supplied to form a connection between the mains supply and 
the rear of the unit. This is configured from the factory with a 30 A / 250 Volt plug. 
 

2.3.1 Proceed as follows: 

 

(i) 

Ensure that there is at least 3” or 7.5 cm clearance at the rear of the 
unit for air flow. 

 

(ii) 

Ensure RF input voltage is not excessive 
a.  The 1 V rms indicated maximum input voltage is 5 times the level of 

the input signal required to achieve maximum output. Input voltages 
in excess of 2 volts peak may permanently damage the instrument. 

 

(iii) 

Connect the output via a 50 ohm coaxial lead and N plug to the load. 

 
(iv) 

Connect  the input  signal via  a 50 ohm coaxial lead and N plug to the 
input connector. 

 

2.3.2 Front Panel Display 

 

The 2400L front panel has a passive LCD display designed for simplicity and 
ease of use.  During initialization, the LCD shows the software revision.  After the 
amplifier is initialized, the LCD indicates Forward Power, Reflected Power, and 
amplifier status (see figure 2.1).     

Pf:___W Pr:___W 

Status:________

 

Figure 2.1 : Front Panel Display 

Where Pf refers to forward power, Pr refers to reverse power, and Status 
indicates “OK” unless there is a fault condition, such as: 

  Overheat (heat-sink temperature is too high for reliable operation) 

  PSU fault (internal fault in the main switching power supply)
