Quantum Data 801GC, 801GF, 801GX manual Hrat, Horizontal RATe, Hres, Horizontal RESolution, 135

HRAT	Horizontal RATe
Classification:	Format parameter setting
Command Syntax: HRAT <frequency in Hz>
Limits:	<frequency in Hz> (floating point accepted)
	typical min = 1000
	typical max = 130000
Query Syntax:	HRAT?
Query Response:	<frequency in Hz> (floating point returned)
Description:	The HRAT command sets the line frequency. Pixel rate is equal
	to the product: HTOT times HRAT. Frame rate is equal to the
	quotient: HRAT divided by VTOT. Field rate is equal to the
	product: SCAN times the frame rate. The HRAT? query returns
	the current horizontal frequency setting.

Other Required Cmds: The FMTU command instructs the generator to use the new setting. The ALLU command updates hardware to the new setting and redraws the test image.

HRES	Horizontal RESolution

Classification: Format parameter setting

Command Syntax: HRES <pixels>

Limits: <pixels> min = 16

max depends on VRES and model of generator

Query Syntax:	HRES?
Query Response:	<pixels>
Description:	The HRES command establishes the number of active pixels per
	line. The HRES? query returns the current setting of HRES.
Other Required Cmds:	The ALLU command updates hardware to the new setting and
	redraws the test image.
