Operation Reference
Function
• MESSAGE NO. is defined as the following where “X” represents the phase setting:
0:   Arbitrary message set from the external controller using the GPIB capability. 
The data must be entered in units of works. Refer to 
‘[SOURce]:PAGing[:FORMat]:{POCSag|FLEX|FTD}:ARBitrary:
DEFine <NR1>, <NR2>,..., <NR1>” and “Using the Buffer Memory for the 
Arbitrary Messages” in Chapter 2.
START FRAME and STOP FRAME are defined in the following menu:
The frames between the START FRAME and STOP FRAME will be transmitted. The allowable 
ranges for both are 000 to 127.
1:   Displays: 01223456[X}
where “X” = “0” for phase A, "1" for phase B, “2” for phase C, “3” for phase D.
2:   Displays: ABCDEFG[X}
where “X” = phase “A”, “B”, “C”, “D”.
3:   Displays: TEST PAGING:XXXXXXX
where “XXXXXXX” = “PHASE A”, “PHASE B”, “PHASE C”, or “PHASE D”.
4:   Displays: ALPHANUMERIC 40CHARS TEST PAGING:XXXXXXX
where “XXXXXXX” = “PHASE A”, “PHASE B”, “PHASE C”, or “PHASE D”.
5:   Displays: 8888888888888888888888888888888888888888
for LCD test with 50 characters of “8”
6:   User-definable message, up to 40 characters long, set from the front panel. 
Enter numeric messages with the keypad. Alphanumeric messages require the 
rad dBµV (SHIFT) key to access the alphabetical characters (blue letters) above 
the keypad. If required alphabetical characters are not available on the front 
panel, send a message from an external controller over GPIB. Refer to 
“[SOURce]:Paging[:FORMat]
:{POCSag\FLEX|FTD}:MESS:DEFine ‘string’” in Chapter 2.
• MESSAGE LENGTH specifies the maximum number of characters that will be sent out and 
displayed in the message field. The allowable range is 1 to 40. After specifying the number of 
characters, press 
MHz dB(m) (ENTER) to save the new value.
When the value of this parameter is equal to or greater than the length of the message, the 
whole message will be sent out.
When the value of this parameter is less than the length of the message, only the characters 
specified by this parameter are output. (For example, if the MESSAGE NO. is 1 (0123456[X]) and 
the MESSAGE LENGTH is 5, the message which is displayed and will be sent out is actually 01234.)
