“!” and a carriage return. (Note that when using HyperTerm, the option to
append a line feed to a received carriage return should be used).
Examples:
FR?
Interrogates current CW frequency and frequency step
FRI
Increments current CW frequency by frequency step
EU
update EEPROM with all user and calibration data
There are two types of data entry used by commands:
Those which expect a fixed length hexadecimal string, and do not require a
terminator character such as a carriage return or enter. Examples:
SM1
Store instrument status to user memory 1
Those which expect a variable length decimal or character string. A decimal
string may contain special characters such as sign, decimal point, and
multiplier, and terminates with a carriage return (enter). The string is always
preceded by a space. Examples:
FR (space) 10.23M (carriage return) enters 10.23MHz
MM (space) FSK (carriage return) sets modulation mode to FSK
RF (space) –18.0 (carriage return)
sets RF level to –18dBm
FST (space) 20k (carriage return)
sets sweep time to 20 secs
The following frequency and time multipliers are accepted:
k, K, M, G
Some commands accept a standard floating point string, which may include
“e” or “E”, however it is never necessary to use the exponent form.
A full list of available commands is given in
Appendix A
. Some of these
commands are intended for development or debug. In this section the
commands likely to be used frequently by the user are described.
3.4 Calibration
All calibration is closed case. There are no adjustments on the PC board.
The following adjustment procedures are possible:
a) Internal reference frequency calibration
