Chapter 1, Using HP-IB

Getting Started

Guideline #3. Avoid program hangs. 

If the program stops or “hangs up” when trying to ENTER a measured value, it is most 
likely that the desired measurement field is not available. There are several reasons 
that can happen: 

1. The screen where the measurement field is located has not been DISPlayed before 

querying the measurement field. 

2. The measurement is not turned ON. 

3. The squelch control is set too high. If a measurement is turned ON but is not 

available due to the Squelch setting, the measurement field contains four dashes 
(- - - -). This is a valid state. The Test Set is waiting for a signal of sufficient strength 
to unsquelch the receiver before making a measurement. If a measurement field 
which is squelched is queried the Test Set will wait indefinitely for the receiver to 
unsquelch and return a measured value. 

4. The RF Analyzer’s Input Port is set to ANT (antenna) while trying to read TX 

power. TX power is not measurable with the Input Port set to ANT. The TX power 
measurement field will display four dashes (- - - -) indicating the measurement is 
unavailable. 

5. The input signal to the Test Set is very unstable causing the Test Set to continuously 

autorange. This condition will be apparent if an attempt is made to make the 
measurement manually. 

6. Trigger mode has been set to single trigger (TRIG:MODE:RETRig SINGle) and a 

new measurement cycle has not been triggered before attempting to read the 
measured value. 

7. The program is attempting to make an FM deviation or AM depth measurement 

while in the RX TEST screen. FM or AM measurements are not available in the RX 
TEST screen. FM or AM measurements are made from the AF Analyzer screen by 
setting the 

AF Anl In

 field to FM or AM Demod.
