HP 8360 manual No error is generated

SCPI COMMAND SUMMARY

The synthesizer uses “bumping” to move unspecified frequency parameters, but if the final value of any of the frequency headers is the result of bumping, then an error is generated since the user is not getting what was specified. This means, to guarantee sequence independence requires sending the frequency pairs in a single message.

Example 1: (present state start = 5 GHz, stop = 6 GHz)

FREQ:STARt 20 GHZ

FREQ:STOP 22 GHZ

an error results since the stop frequency is bumped. the final sweep does not generate an error

(20 to 22).

Example 2: (present state start = 5 GHz, stop = 6 GHz)

FREQ:STOP	22 GHZ	no error is generated,
		start frequency is unchanged.
FREQ:STARt	20 GHZ	still no error.

Example 3: (present state start = 5 GHz stop = 6 GHz)

FREQ:STARt 20 GHZ;STOP 22 GHZ	both are fine, no errors.
FREQ:STOP 22 GHZ;STARt 20 GHZ

•FREQuency:CENTer <num>[freq suffix]lMAXimumlMINimumlUPlDOWN

•FREQuency:CENTer? [MAXimumMINimum]

Sets and queries the center frequency. The *RST value is (MAX + MIN)/2.

•FREQuency[:CWl:FIXed] <num>[freq suffix]lMAXimumlMINimumlUPlDOWN

•FREQuency[:CWl ? [MAXimumMINimum]

•FREQuency[:FIXed]? [MAXimumMINimum]

Sets and queries the CW frequency. This does not change the swept/CW mode switch. *RST value is (MAX + MIN)/2 .

See FREQ:CENTER for more information.

•FREQuency[:CW]:AUTO ONlOFFlllO

•FREQuency[:FIXed]:AUTO ONlOFFlllO

•FREQuency[:CWl:AUTO?

•FREQuency[:FIXed]:AUTO?

Sets and queries the CW/center frequency coupling switch. This switch keeps the two functions coupled together when ON. Changing one of them, changes both. *RST setting is OFF. See FREQ:CENTER for more information.
