Communication setup: Press MENU KEY twice and select I/O SETUP MODE, then enter the
speed rate. Best condition of data communication is 9600 BPS.
7. Frequency Setup
1) Frequency Setup Format Type
COMMAND + DATA(ASC CODE) + CR(0DH)
Ex.) MARKER frequency on 2000.10625 MHz
MARKER frequency on 12.5 kHz
MARKER frequency on 40.0 MHz
DIFFERENCE STEP on 130.0 MHz
2) Setting Value of the Frequency Setup can be changed by SCAN MODE
① MANUAL MODE
When setting up the MARKER frequency, tune in the center frequency to the MARKER
frequency. Set up the MARKER on 80CH.
② CH MODE
③ SEARCH MODE
Entering first frequency value will be set up on START frequency, and Second frequency
value will be set up on STOP frequency.
Ex.) START frequency on 500.0MHz, STOP frequency on 600.0MHz
"K0500.0" CR: START, "K0600.0" CR: STOP
3) Frequency Output Format
ASC DATA + CD(0DH)
Ex.) MARKER frequency
STEP frequency
DIFFERENCES STEP frequency
COUNTER frequency
Instrument outputs COUNTER Value per 512ms in RUN mode
