Setting RBW

Command : RBW* * *

2650A, 2652A, 2658A :

( * * * * = 3K, 10K, 30K, 100K, 300K, 1M, 3M, AUTO, ALL [ unit : Hz ])

2651 :

( * * * * = 3K, 9K, 30K, 120K, 300K, 1M, 3M, AUTO, ALL [ unit : Hz ])

* ALL : The optimum RBW, VBW, and sweep time are set based on the frequency

span.

* AUTO : The optimum RBW is set based on the frequency span.

Example: RBW3M

Query: RBW?

Setting VBW

Command : VBW* * * *

( * * * * = 100, 300, 1K, 3K, 10K, 30K, 100K, 300K, 1M, AUTO, ALL [ unit : Hz ] )

* ALL : The optimum RBW, VBW and sweep time are set based on the frequency

span.

* AUTO : The optimum RBW is set based on the frequency span.

Example: VBW300

Query: VBW?

Selecting Measuring Function

Command : MEAS* * *

(* * * = CP, ACP, OBW, EF, MF,

FC, OFF)

Example: MEASOBW

(To change measuring function when in

a different measurement mode, set function OFF first by sending MEASOFF)

Query: MEAS?

Request measuring result

Command : MEASRES

* Example of measuring result

Channel power measurement ----- POW: - 25.5 dBm

Adjacent channel power measurement ----- L: - 47.7 dBc U: - 48.3 dBc

Occupied bandwidth measurement ----- C: 1.45 G W: 20.00 k

Frequency counter ----- FC: 2400.0000 M

* If the frequency counter is not installed, “Invalid for F/C” is responded.

* If the level of spectrum is low and unmeasurable, “Non Signal” is

responded.
