Appendix 1. Error Messages - TTI TGR2050 Bedienungsanleitung

Error messages are given when a system fault is found or an illegal setting is attempted; the
previous setting is retained if an OUT OF RANGE value is sent via a remote interface.
Each error message has a number; only this number is reported via the remote control interfaces.
The following is a complete list of messages as they appear on the display.
Error Message No.
Error message numbers are not displayed but are placed in the Execution Error Register where
they can be read via the remote interfaces.

Appendix 1. Error Messages

Displayed at power up if a checksum error is
encountered when reading calibration
To set
constants from EEPROM. A key press is
necessary to continue operation but the
instrument will almost certainly be outside
specification.
Displayed if default calibration constants
could not be successfully written into the
EEPROM following an EEPROM read error. A
key press is necessary to continue operation
but operation is unpredictable.
Displayed at power up if a checksum error is
encountered when reading set up information
from non–volatile RAM. Operation continues
automatically after three seconds delay.
Displayed if a REMOTE command attempts
to set any parameter to a value which is
beyond its acceptable range of values.
Operation continues automatically after three
seconds.
Displayed if an attempt is made to retrieve an
instrument set up from a store which has not
yet been programmed. In LOCAL mode a key
press is necessary to continue operation. In
REMOTE mode operation continues
automatically after three seconds delay.
Displayed if both MOD and FM (or PM) are
turned on with a peak deviation already set to
greater than that permitted for the current
carrier frequency. The entered deviation is
remembered and is restored when the carrier
frequency is changed or MOD ON/OFF
and/or FM (or PM) are turned off.
Displayed if both RF OUT and AM are turned
on with the output level already set to
AM ON
>+1dBm. The level is permanently changed
to +1dBm.
