Tektronix OA 5000 *TST? (Query Only)

Commands

Programming

3 --- 3 2

<NRf> specifies the attenuationvalue to be stored. The range for the attenu-

ation value is0 ≤<NRf> ≤60. 00. Allattenuation values associated with the

STORe command and query formsare in absolute dB and never include the

REFERENCE value, even if the frontpanel display shows that the OA 5000 is

set to ATT-REFmode.

STORE1?

returns the attenuation value storedin register 1, in the form:.

:STORE1 <NRf>

STORE1 20.00

sets the attenuation value instored register 1 to 20.00 dB.

STORE2

stores the current attenuation valuein stored register 2.

*TST? (Query Only)

The *TST? (Self-Test)query runs the OA 5000 internal self-test and reports

the results. The self-test doesnot require operator interaction and does not

create bus conditionsthat violate IEEE Std 488.1/488.2 standards. When

complete, the OA 5000 returns to the state itw as inj ust priorto the self-test.

The test response is a value <NR1> as describedin Table 3-7.

The *TST? query can take 5 s econds or more to respond.
