[:SOURce]:FLEX:PHASe A | B | C | D | AB | AC | AD | BC | BD | CD | ABC | ABD | ACD | BCD | ABCD |
The command determines in which phase (A to D) the message is to be transmitted. Since each
frame lasts 1.875 sec independent of the modulation and more data can be transmitted at bit
rates higher than 1600 bps, several independent channels ("phases") are bit-multiplexed. With
1600 bps, the message is transmitted for every setting in phase A. With 3200 bps, the message is
transmitted in phase A if A and B are set, and transmitted in phase C if C and D are set. With
6400 bps, the message is transmitted in all the four phases depending on the relevant setting.
Each pager is set to one phase. The phase can be calculated from the CAPCODE of a pager as
shown below:
Phase = (Integer(CAPCODE/4)) modulo 4, with 0=A, 1=B, etc.
Example: :SOUR:FLEX:PHAS A *RST value is A
[:SOURce]:FLEX:PHASe:AUTO ON | OFF
This command determines whether the phase setting is coupled to the CAPCODE.
ON The phase is adjusted to the value contained in the CAPCODE whenever the
CAPCODE is used (see FLEX standard).
OFF Using the CAPCODE has no effect on the phase.
Example: :SOUR:FLEX:PHAS:AUTO ON *RST value is ON
[:SOURce]:FLEX:MESSage
Under this node there are commands to set the destination address and to determine the useful
data of the message.
[:SOURce]:FLEX:MESSage:CAPCode "Capcode string"
Input value of the CAPCODE of the pager to be called as printed on the receiver. CAPCODE is
defined in the FLEX standard. It contains the addresses of the receiver as well as frame and
phase information.
Example: :SOUR:FLEX:MESS:CAPC "A0000001" *RST value is "A0000001"
[:SOURce]:FLEX:MESSage:CATegory ALPHanumeric | SECure | BINary | NUMeric | SNUMeric |
TONE
The command determines the category of the message to be transmitted.
ALPHanumeric Alphanumeric message
SECure Secured alphanumeric message
BINary Binary message
NUMeric Numeric message (with
≤
3 figures = "short message" according to FLEX standard)
SNUMeric Special numeric message
TONEOnly-tone message
Example: :SOUR:FLEX:MESS:CAT NUM *RST value is TONE
[:SOURce]:FLEX:MESSage:ALPHanumeric|SECure
This node contains commands for the determination of the contents of the alphanumeric and the
secured messages. There is one common character set for the two types of messages. These
commands can only be activated if FLEX:MESSage:CATegory ALPHanumeric or SECure is
selected.
