Compatibility:

2090

Description:

is either in N1 (XXX) or N2 (XXX.X) format depending upon the current
numeric mode. Negative values are preceded by a "-" minus sign.

Devices:

Towers

[-]XXX[.X]

VS?

Syntax:

UV?

Response:

Value of the upper limit for the vertical polarization
in centimeters.

CALL ibwrt (TowerUD%, "UV?")

' Query vertical upper limit

CALL ibrd (TowerUD%, rdbuf$)

' Read response

Description:

Syntax:

Response:

Indicates if a device is capable of variable speed
control:

Example:

Compatibility:

2090 (Firmware Rev 3.00)

Queries the variable speed capability of the device.

Devices:

Towers, Turntables

VS?

Device supports variable speed

Device is not capable of variable speed control

CALL ibwrt (TowerUD%, "VS?")

' Is device variable speed?

CALL ibrd (TowerUD%, rdbuf$)

' Read response

Compatibility:

1050, 1060
Queries the turntable's clockwise limit. The value returned is either in N1
(XXX) or N2 (XXX.X) format depending upon the current numeric mode.
Negative values are preceded by a "-" minus sign. This command is obsolete.
On the models 1050 and 1060, this command changed the front panel to
display the clockwise limit and prepared the controller to respond to all future
reads with that limit. This is not compatible with the IEEE 488.2 standard;
the program must send the WL command before each read. For programs
which will not be used with a model 1050 or 1060, use the WL? command

Response:
Example:

' Query turntable clockwise

' Read response

Description:

Devices:

Turntables

Syntax:

[-]XXX[.X]

Value of the clockwise limit setting in degrees.

CALL ibwrt (TableUD%, "WL")

' limit

CALL ibrd (TableUD%, rdbuf$)
