H-8
ERRSTR?
Purpose To request the error number and error response string.
Format ERRSTR?
Response <error_number>, <error_string>
Description The ERRSTR? query returns two responses separated by a comma. The first response is the error num-
ber, and the second is the message explaining the error.
Unlike the HP3458, Model 2002 errors are returned in the order generated instead of the error reg-
ister bit order. No error register bits are cleared until the last error is read at which time all bits are
cleared.
FREQ
Purpose To select the frequency measurement function.
Format FREQ <max_input>,<%_resolution>
Parameter <max_input> 1V, 10V, or 100V
<%_resolution> Ignored
Description The FREQ command selects the frequency measurement mode for the Model 2002. The first param-
eter selects a maximum input level of 1V, 10V, or 100V, while the second parameter is not supported
by the Model 2002 and will be ignored.
Example FREQ Select frequency.
FREQ 10 Select frequency, 10V maximum input.
FSOURCE
Purpose To select the signal type for frequency or period measurements.
Format FSOURCE <source>
Parameter <source>
<source> parameter Numeric equivalent Description
ACV 2 AC voltage
ACDCV 3 AC+DC voltage
ACI 7 AC current
ACDCI 8 AC+DC current
Default ACV
Query FSOURCE? Returns the present frequency source.
Description The FSOURCE command specifies the type of signal to be used as the input signal for frequency or
period measurements. Signal types include AC voltage, AC current, AC+DC voltage, and AC+DC
current.
