400 Query error
This code indicates only that a Query Error as defined in IEEE 488.2 11.5.1.1.7 and 6.3
has occurred.
Error
−
410 Query INTERRUPTED
Indicates that a condition causing an INTERRUPTED Query error occurred (see IEEE
488.2, 6.3.2.3). For example, a query followed by DAB or GET before a response was
completely sent.
This message appears when you query a measurement without immediately entering the
returned value into a variable. For example, the following program lines query the TX
Frequency measurement and enter its value into a variable (Rf_freq):
OUTPUT 714;"MEAS:RFR:FREQ:ABS?"
ENTER 714;Rf_freq
Error
−
420 Query UNTERMINATED
Indicates that a condition causing an UNTERMINATED Query error occurred (see IEEE
488.2, 6.3.2.2.). For example, the device was addressed to talk and an incomplete program
message was received.
This message usually appears when trying to access a measurement that is not active. For
example, you cannot query the DTMF Decoder measurements from the DUPLEX TEST
screen, or query the TX Frequency measurement when the TX Freq Error
measurement is displayed.
Error
−
430 Query DEADLOCKED
Indicates that a condition causing a DEADLOCKED Query error occurred (see
IEEE 488.2, 6.3.1.7). For example, both input buffer and output buffer are full and the
device cannot continue.
Error −440 Query UNTERMINATED after indefinite response
Indicates that a query was received in the same program message after a query requesting
an indefinite response was executed (see IEEE 488.2, 6.5.7.5.7).
