ESHSx; ESVSx; ESPC; ESCS30: Remote control: How to read out the frequencies of a transducer set.			FAQ overview
Question:		No matter which set I select - with the following script, I always get the readout of the set I manually edited. TRANSDUCER:SET 1 TRANSDUCER:SET:RANGES:SELECT 1 TRANSDUCER:SET:RANGES:START? The return value should be the Start value of Range 1 of Set 1, but when I edit Set 2 I get the Start value of Range 1 of Set 2.
Answer:		Selecting a range opens the edit mode of the transducer, which produces wrong values. You have to leave the edit mode with a save command. Below you will find a program that shows how to read out the frequencies of a range: Private Sub Connect_Click() Rem Dimensions Dim Buffer1 As String * 2000 Dim Buffer2 As String * 2000 Dim Handle As Integer Me.MousePointer = vbHourglass: DoEvents 'change cursor to hourglass Rem Select the receiver ibdev 0, 18, 0, 12, 1, 0, Handle '<<<<< Rem Select the transducer set 1 ibwrt Handle, "TRANSDUCER:SET 1" '<<<<< Rem Select the range 1 ibwrt Handle, "TRANSDUCER:SET:RANGES:SELECT 1" '<<<<< Rem By selecting a range you also select the edit mode, Rem save the set to leave the edit mode ibwrt Handle, "TRANSDUCER:SET:SAVE" '<<<<< Rem read out the start frequency ibwrt Handle, "TRANSDUCER:SET:RANGES:START?"
