Remote Operation<br />
3.3.3 Mode Selection and Control<br />
This section describes the various modes of operation available with the PPM, with the exception of the<br />
sub-mode functions of the Graph Mode. These are described in Section 3.3.5.<br />
Commands or functions that affect a specific mode of operation are either given or referred to in the<br />
following command listings. It should be kept in mind that it is sometimes possible to combine modes,<br />
therefore care must be taken to observe the rules and arguments set forth.<br />
Select Log or Linear <strong>Power</strong> Measurement Format Commands<br />
DBMW<br />
dBm measurement format display and GPIB output.<br />
WATT Linear measurement format (mW) display and GPIB output.<br />
Typical Program Line:<br />
OUTPUT 704;WATT<br />
Select Measurement Mode Commands<br />
(Except Graph and Ratio Modes)<br />
CW<br />
CWPA<br />
CWPB<br />
<strong>Power</strong> Commands<br />
CW power, channel A<br />
CW power, channel B<br />
CWAB CW power, channels A & B<br />
A CW related command is:<br />
AVCWnnn<br />
Select number of averages n for CW power measurements. Higher numbers reduce noise effects and<br />
stabilize readings at low power levels.<br />
(n = number between 1 and 999)<br />
<strong>Peak</strong> <strong>Power</strong> Commands<br />
The <strong>Peak</strong> <strong>Power</strong> Mode must be used very carefully. <strong>Power</strong> measurements in this mode depend on the<br />
occurrence of a trigger, and the positioning of the cursor on the pulse to be measured. For more<br />
information, refer to Selecting <strong>Peak</strong> <strong>Power</strong> Operation in Section 3.2.5.<br />
To enter the <strong>Peak</strong> <strong>Power</strong> Mode use:<br />
PKPA<br />
PKPB<br />
PKAB<br />
<strong>Peak</strong> Mode for Channel A only<br />
<strong>Peak</strong> Mode for Channel B only<br />
<strong>Peak</strong> Mode for Channels A & B<br />
