Setting the Trigger Source | HP E1429A instruction

Setting the Trigger Source

The register used to set the digitizer’s trigger (sample) source is listed below.

∙Trigger source register base + 4D16

Procedure

Sending an Arm Immediate Signal

The trigger source can be set/changed when the digitizer is in the idle state or while it is initiated.

1.Setting/changing the trigger source while in the idle state:

A.Write the decimal equivalent bit pattern to the trigger source register while retaining the settings of the other bits

(base + 4D16).

2.Setting/changing the trigger source while initiated:

A.Suspend the sample trigger by setting bit 7 of the trigger source register (base + 4D16) to ’1’ . Retain the settings of the other register bits.

B.Write the decimal equivalent bit pattern for the desired trigger source to the trigger source register.

C.Enable the sample trigger by setting bit 7 of the trigger control register (base + 4D16) to ’0’ . Retain the settings of the other register bits.

An arm immediate signal arms the digitizer, overriding arm source ’hold’ and any programmed arm delay. The registers used to send an arm immediate signal are listed below.

∙Abort and Arm Immediate register base + 4116

∙Arm Status register

base + 4316

Procedure 1. Determine the arm state:

A. Read bits 7 and 5 of the arm status register (base + 4316). If bit 7 is ’1’, the digitizer is already armed and it is not necessary to send an arm immediate. If bit 5 is ’1’, arm immediate must not be sent since the pre-arm reading count has not been reached.
