1
Displays carrier frequency in kHz or MHz, and RF level in dBm or mV. Alternately
displays error codes and messages. The display is eight characters wide and
displays the measurements of carrier level and frequency. In ratio mode the fre-
quency can be displayed in % or delta frequency and the level in % or dB.
AUDIO display
2
AUDIO display is four characters wide and it displays modulation frequency in Hz
or kHz and distortion in % or dB SINAD. In ratio mode distortion and SINAD can
be displayed in % or dB and the audio frequency can be displayed in % or delta
frequency.
MODULATION display
3
The MODULATION display is four characters wide and it displays modulation in %
for AM, kHz for FM deviation, and RAD for PM deviation. Also displays ratio in %
or dB.
BUS Status display
4
Displays current IEEE-488 bus status; REM (remote enabled), LSN (listener ad-
dressed), TLK (talker addressed), and SRQ (service request active).
SPCL/PRGM display
5
The SPCL/PRGM display is an entry only display which is two characters wide and
display the current program number or selected special function. Units are PRGM
for program number, SPCL for special function, and ADRS for IEEE-488 bus ad-
dress. Also included a LINE annunciator which indicates that ac power is applied.
FREQ key
6
Selects carrier frequency as the active function. Use before setting carrier fre-
quency or to activate carrier frequency display.
LEVEL key
7
Selects carrier level as the active function. Use before setting carrier level or to
activate the level display.
AUTO key
8
Forces the selected function to the measurement mode. Not active for the PRGM
and SPCL functions.
