When using the GPIB interface, the REN, LLO, and GTL commands are not implemented. The I command is used by both interfaces to set the
The J command sets the RS232
The K command simulates a front panel key press. The effect is exactly the same as pressing the selected key once. The parameter n is required.

L m {,n}The L command sets and reads the status of the line notch filters. If m is "1", then the 1X line notch is selected, if m is "2", the 2X line notch is selected. The parameter m is required. If n is "1", the L command sets the selected filter in. If n is "0", the selected filter is taken out. If n is absent, the status of the selected filter is returned.
M {n}If n is "1", the M command sets the reference mode to 2f. If n is "0", the reference mode is set to f. If n is absent, the reference mode is returned.
N {m}If m is "1", the N command sets the ENBW to 10 Hz. If m is "0", the ENBW is set to 1 Hz. If m is absent, the ENBW setting is returned.
O {n} {,v}If n is "1", the O command turns the offset on. If n is "0", the offset is turned off. If n is absent, the offset status (on or off) is returned. (The value of the offset is read using the S and Q commands.) If n is included, then v may also be sent. v is the offset value up to plus or minus full scale in units of volts. For example, to offset half of full scale on the 100 ∝ V sensitivity, v should be
If v is absent, the P command returns the phase setting from
